When you enter Ultra-@TeX{} mode (say, if you have followed the installation instructions (@pxref{Installation}) so that you enter Ultra-@TeX{} whenever you open a @TeX{} file), Emacs constructs a list of @TeX{} commands. Then when you hit @kbd{\}, Emacs does lightning completion on the elements of this list. I'll describe what lightning completion is, and I'll explain how Emacs constructs this list of commands. @menu * Lightning completion:: An overly brief introduction to lightning completion * Making a list:: Checking it twice, etc. @end menu @comment --------------------------------------------------------- @node Lightning completion, Making a list, Completion, Features @comment node-name, next, previous, up @section Lightning completion @cindex Lightning completion @cindex Completion @vindex ultex-complete-idle-time @vindex lc-complete-idle-time @vindex lc-clean-up Here is an example of lightning completion: suppose that the list of commands that Emacs knows about only contains the following: @example \xrightarrow@{@}, \xleftarrow@{@}, \Rightarrow @end example If I hit @kbd{\}, then @samp{\} is inserted into the buffer, and lightning completion starts. If I then hit @kbd{R}, then after a delay (of length governed by the variable @code{ultex-complete-idle-time}) @samp{Rightarrow} is inserted and completion ends (this all happens because there is only one valid completion starting @samp{\R}). If I hit @kbd{x} instead of @kbd{R}, then @samp{x} gets inserted. Then I can either hit @kbd{r} or @kbd{l}, resulting, after a delay, in either @samp{\xrightarrow@{@}} or @samp{\xleftarrow@{@}}. (The aforementioned delay is new in version 0.50 of this package. By default, it is equal to @code{lc-complete-idle-time-default}, a variable documented in the Lightning Completion Manual (@pxref{Overview, , Lightning completion, light.info, Lightning Completion Manual}). To get the old behavior of immediate completion, set the variable @code{ultex-complete-idle-time} to 0.) Using the same example, if I start by hitting @kbd{\}, if I hit any printing character other than @kbd{x} or @kbd{R}, then after a delay, Emacs beeps because there is no valid completion starting with that character, and (depending on the value of the variable @code{lc-clean-up}) either that character is inserted or nothing is inserted. I can always stop lightning completion prematurely by hitting @kbd{C-c}; this is one way to insert @TeX{} commands that Ultra-@TeX{} doesn't know about. There is more to lightning completion. @xref{Overview, , Lightning completion, light.info, Lightning Completion Manual}, for a full description. @comment --------------------------------------------------------- @node Making a list, Defining new commands, Lightning completion, Features @comment node-name, next, previous, up @section Making a list @findex ultex-reset-current-alist @findex ultex-grab-defs @findex ultex-grab-bibs @vindex ultex-tree-file @vindex ultex-extra-tree-files @vindex ultex-also-load @vindex TeX-master @vindex ultex-alist-local-flag @cindex Making a list @cindex List of @TeX{} commands @cindex @TeX{} command list @cindex @TeX{} command files @cindex Files of @TeX{} commands @cindex Scanning buffer for commands As I said earlier, when Emacs enters Ultra-@TeX{} mode, it constructs a list of @TeX{} commands, and it uses this list for its completion table. The list is built from two pieces: first of all, the user should have a @dfn{textree} file, containing the @TeX{} commands she typically uses. Remarks: @enumerate @item A sample textree file, @file{textree.el}, is included in the Ultra-@TeX{} package. @item The path name of this file is stored in the variable @code{ultex-tree-file}. @xref{Installation}, for how to set this, if you're not sure. @item If you're in Ultra-@TeX{} mode, you can run the command @code{ultex-new-cs} to specify a new command sequence to be entered into the textree file. @xref{Defining new commands}, for more information on this. (Alternatively, the textree file is an Emacs lisp file, so you can edit it directly if you're comfortable with Emacs lisp.) @item If you're in Ultra-@TeX{} mode, you can run the command @code{ultex-delete-csname-from-tree-file} to specify a command sequence to be deleted from the textree file. @xref{Defining new commands}, for more information on this, too. @end enumerate Now, Emacs scans the current buffer (the one which is using Ultra-@TeX{} mode), looking for commands of the forms @example \documentclass@{bozo@} \documentstyle@{bozo@} \usepackage@{bozo@} @end example When it finds any such lines, it examines the list @code{ultex-extra-tree-files} to see if there is an associated file of commands for that class, style, or package, and if there is, if the main file @file{textree.el} should also be loaded. It loads each one of these files, along with the main one if appropriate. Remarks: @enumerate @item @xref{Installation}, to see how to set the variable @code{ultex-extra-tree-files}. @item If the current buffer has more than one command file associated to it, if you run @code{ultex-new-cs} to add a new command, Emacs will ask which file to add it to. Similarly, if you run @code{ultex-delete-csname-from-tree-file} to delete a command, if that command appears in more than one file, Emacs will ask you which one to delete it from. @item The variable @code{ultex-also-load} may contain the name of a command file to load in addition to any others which have been specified. This is intended for use as a local variable; in other words, to use it, you should have lines like this at the end of your @TeX{} document: @example %% Local variables: %% ultex-also-load: "~/emacs/other-ultex-commands.el" %% End: @end example @end enumerate After this has been done, Emacs scans the current buffer, looking for more commands. It finds commands in the following ways: @itemize @bullet @item If the buffer contains a @TeX{} command of the form @example \newcommand@{\bozo@}[3]@{blah blah blah@} @end example @noindent (or @samp{\renewcommand...} or @samp{\providecommand...}) then Emacs adds the string @samp{\bozo@{@}@{@}@{@}} to its list of @TeX{} commands (there are three sets of brackets because the @samp{3} in the square brackets tells La@TeX{} that @samp{\bozo} takes 3 arguments. If you then use lightning completion to insert @samp{\bozo@{@}@{@}@{@}} in the buffer, the point is placed inside the first set of brackets. Hitting the @key{RET} key moves you to the next set of brackets (@pxref{Smart return key}). @item If the buffer contains a @TeX{} command of the form @example \DeclareMathOperator@{\clown@}@{Clown@} @end example @noindent then Emacs adds @samp{\clown} to its list. @item If the buffer contains a @TeX{} command of the form @example \newenvironment@{circus@} @end example @noindent (or @samp{\renewenvironment@{circus@}}) then Emacs adds @example \begin@{circus@} \end@{circus@} @end example @noindent to the list; when Ultra-@TeX{} inserts this in your buffer, it puts the point on the blank line. @item If the buffer contains a @TeX{} command of the form @example \newtheorem@{dumb-lemma@}[thm]@{Lemma@} @end example @noindent then Emacs adds @example \begin@{dumb-lemma@}\label@{@} \end@{dumb-lemma@} @end example @noindent and it puts the point inside the argument for @samp{\label}. If you don't want a label, just hit the @key{RET} key (@pxref{Smart return key}). @item If the buffer contains a string of the form @example \label@{ling-ling@} @end example @noindent then Emacs adds @samp{\ref@{ling-ling@}}, @samp{\pageref@{ling-ling@}}, and @samp{\eqref@{ling-ling@}} to its list. @end itemize The above scanning is done by the function @code{ultex-grab-defs}. The following is done by @code{ultex-grab-bibs}. @itemize @bullet @item Emacs scans the bibliography for bibliographical keys: if the buffer contains @samp{\begin@{thebibliography@}} and @samp{\end@{thebibliography@}} commands, Emacs looks between them for commands of the form @example \bibitem@{bib-key@} Bozo the Clown, \emph@{How to write bad emacs lisp code@}, ... @end example @noindent When it finds such a command, it adds @samp{\cite@{bib-key@}} and @samp{\nocite@{bib-key@}} to the list. If your buffer is associated to a file, @file{file.tex}, then Emacs does exactly the same scanning on the file @file{file.bbl}. Lastly, if the buffer contains a command @example \bibliography@{bib-data-base@} @end example @noindent then Emacs looks for a file @file{bib-data-base.bib}; if it finds it, it adds @samp{\cite} and @samp{\nocite} for all of the keys in it. @end itemize Emacs does all of this scanning recursively: @itemize @bullet @item Whenever Emacs finds commands like @example \input@{bozo@} \include@{bobo@} @end example at the start of a line, then Emacs scans the files @file{bozo.tex} and @file{bobo.tex} for their commands and labels. If these commands are not at the start of the line (they have spaces or tabs in front of them, say), then the files are not scanned. @item Whenever Emacs finds a line like this at the start of the file: @example %% -*- TeX-master: "main.tex"; -*- @end example or lines like this at the end of the file: @example %% Local variables: %% TeX-master: "main.tex" %% End: @end example then Emacs scans the file @file{main.tex} for its commands and labels (and any files included or input into them, too). @end itemize A few remarks: @enumerate @item Emacs learns these command only temporarily---Emacs forgets them between editing sessions (which seems appropriate---I don't want commands I've defined specifically in one @TeX{} document to be valid completions every time I edit any @TeX{} document). @item The way things are currently set up, each buffer maintains its own list of @TeX{} commands. This behavior is controlled by the variable @code{ultex-alist-local-flag}. If you want to change this---if you want Ultra-@TeX{} to complete on commands defined in document A when you're editing document B---then customize the variable @code{ultex-alist-local-flag} (in the customization group "ultra-tex-commands". @item Hitting @kbd{C-c C-r} runs the command @code{ultex-reset-current-alist}, which resets the list to its default (the contents of the appropriate textree files) in the current buffer, or in all @TeX{} buffers if @code{ultex-alist-local-flag} is off. @item The method of scanning for new commands is oriented towards La@TeX{}, rather than plain @TeX{}. Sorry about that. @item To avoid the recursive grabbing of commands from input or include files, just have a leading space or tab before the command: Emacs only does the recursive grabbing if the line begins with @samp{\input} or @samp{\include}. @end enumerate @menu * Defining new commands:: How to put new @TeX{} commands into the textree file (and how to remove them, too). @end menu @comment --------------------------------------------------------- @node Defining new commands, Dollar signs, Making a list, Features @comment node-name, next, previous, up @section Defining new commands @findex ultex-new-cs @findex ultex-delete-csname-from-tree-file @findex ultex-delete-csname @cindex Defining new commands @cindex New commands @cindex Deleting commands @cindex Removing commands @cindex Commands--adding @cindex Commands--removing If you want to add a command to your textree file (hence permanently adding the command to the list of @TeX{} commands on which Ultra-@TeX{} completes), you should run the command @code{ultex-new-cs}. In Ultra-@TeX{} mode, this is bound to the key sequence @kbd{C-c C-n}. When you do this, a new buffer, @samp{*TeX Completions Edit*}, is opened in another window, and a backslash is inserted (just to get you started). You type in your new command, including all the brackets and braces you want, put the cursor where you want the point to be when this string is inserted in your @TeX{} document, and then hit @kbd{M-C-c} to exit. You will be asked if you want to use this command in math mode exclusively; if you say yes, you will get an error message if you try to use it outside of a math environment (but the command will still be inserted). If the current buffer is using more than one file of @TeX{} commands, you will be asked in which file to store the command. For example, if I wanted to add the command @samp{\sqrt[]@{@}} to my textree file, I would hit @kbd{C-c C-n} to run @code{ultex-new-cs}, then type @kbd{sqrt[]@{@}} in the new buffer (remember, the backslash is already there). Then I would put the cursor inside the brackets, and hit @kbd{M-C-c}. This will add the line @example ("\\sqrt[]@{@}" -3 . ultex-math-mode) @end example @noindent to the appropriate textree file. The first entry here is the command, the second entry is the number of characters the point is offset from the end of the string, and the last entry says that this command should only be used in a math environment. If your textree file has some commands you don't want, you can run the command @code{ultex-delete-csname-from-tree-file}. This prompts you for a command and then deletes it from the textree file. If the command is in more than one of the textree files associated to this buffer, you are asked to specify the file, also. You can also edit the command files by hand. If you have want to get rid of the command @samp{\sqrt[]@{@}}, open the textree file, and look for a line like @example ("\\sqrt[]@{@}" -3 . ultex-math-mode) @end example @noindent Once you have found it, delete it and save the file. (In case you're not familiar with emacs lisp and you want to do this: just be careful to delete a region starting with a left parenthesis and ending with its matching right parenthesis. Of course, if you're nervous about it, make a backup of your textree file, and then play around.) If you want to disable a @TeX{} command for this editing session (in this buffer only, if you have made @code{ultex-current-alist} local), call the function @code{ultex-delete-csname}, bound to the key sequence @kbd{C-c C-d}. You are prompted for a @TeX{} command you don't want, and the one you select is removed, temporarily, from the master list. @comment --------------------------------------------------------- @node Dollar signs, Smart return key, Defining new commands, Features @comment node-name, next, previous, up @section Dollar signs @vindex ultex-dollar-back @vindex ultex-dollar-array @cindex Dollar signs @cindex Math environments When @TeX{} sees text between two dollar signs (like @samp{$x=y$}), it processes that text in math mode. There are a number of other ways of typesetting mathematics, such as the @samp{equation} environment and the @samp{eqnarray} environment. In Ultra-@TeX{} mode, you can get at all of these things using the @kbd{$} key. Here is what @kbd{$} does: @itemize @bullet @item If you hit @kbd{$} once, Emacs inserts a pair of dollar signs and places the point between them. @item If you hit @kbd{$} again, Emacs inserts @example \[ \] @end example @noindent and puts the point on the blank line. @item If you hit @kbd{$} again, Emacs inserts @example \begin@{equation@}\label@{@} \end@{equation@} @end example @noindent and puts the point in the argument of @samp{\label}. @item Next comes @example \begin@{equation*@} \end@{equation*@} @end example @noindent with the point on the blank line, then @example \begin@{equation@}\label@{@}\n\n\end@{equation@} @end example @noindent then @example \begin@{equation*@}\n\n\end@{equation*@} @end example @noindent then @example \begin@{align@}\label@{@} \end@{align@} @end example @noindent then @example \begin@{align*@} \end@{align*@} @end example @noindent then @example \begin@{gather@}\label@{@} \end@{gather@} @end example @noindent then @example \begin@{gather*@} \end@{gather*@} @end example @noindent then @example \begin@{multline@}\label@{@} \end@{multline@} @end example @noindent then @example \begin@{multline*@} \end@{multline*@} @end example @noindent @item If you hit @kbd{$} again, you go back to @example \[ \] @end example @noindent and (aside from the fact that you've skipped the first option---a pair of dollar signs) the whole thing starts over again. If you would rather start over again with @samp{$$} instead, then set the variable @code{ultex-dollar-back} to 0. @end itemize This works even if the math environment is not empty. For example, if you have @example \begin@{equation@}\label@{wiles@} x^@{n@} + y^@{n@} = z^@{n@} \end@{equation@} @end example and you hit @kbd{$}, then you get @example \begin@{equation*@} x^@{n@} + y^@{n@} = z^@{n@} \end@{equation*@} @end example Hitting @kbd{$} again gives @example \begin@{align@}\label@{wiles@} x^@{n@} + y^@{n@} = z^@{n@} \end@{align@} @end example If you ever just want a single dollar sign, you can either type @kbd{C-q $}, or hit @kbd{$} and then delete one of the two dollar signs that were just inserted (using @kbd{C-d} or @key{DEL}, for instance). You can change the strings that get inserted by customizing the variable @code{ultex-dollar-array} (customization group "ultra-tex-environments"). @comment --------------------------------------------------------- @node Smart return key, Fonts, Dollar signs, Features @comment node-name, next, previous, up @section Smart return key @cindex Smart return key @cindex Return key The @key{RET} key in Ultra-@TeX{} mode tries to move the point forward by the ``appropriate amount.'' @itemize @bullet @item If you are editing ordinary text, hitting @key{RET} moves the point past the next word. @item If the point is to the left of a brace @samp{@{}, hitting @key{RET} moves the point to the right of the brace. @item Suppose the point is inside a pair of braces. If the braces contain several words, hitting @key{RET} moves forward a word. If the braces only contain one word, or if the point is in the last word enclosed by the braces, hitting @key{RET} moves you to just outside the braces. @item There is similar behavior with brackets @samp{[]} instead of braces, with one exception: since brackets are used for optional arguments to @TeX{} commands, if the point is inside an @emph{empty} pair of brackets, hitting @key{RET} will delete the pair. This way, you can use lightning completion to insert a command with lots of optional arguments, and you only have to hit RET to get rid of the ones you don't want. (For example, you don't need separate entries in your textree file for @samp{\sqrt[]@{@}} and for @samp{\sqrt@{@}}.) @item Similarly, if the text looks like @samp{\label@{@}}, and the point is inside the braces, hitting @key{RET} will delete the string @samp{\label@{@}}. @item Since Ultra-@TeX{} completes on bibliographical keys, it assumes you ordinarily don't want to add anything to the argument of @samp{\cite}. So if the text looks like @samp{\cite[bozo]@{clown@}}, if the point is anywhere inside the brackets, hitting @key{RET} moves the point past @samp{@{clown@}}. If the brackets had been empty, hitting @key{RET} would have deleted them, and then moved the point past @samp{@{clown@}}. If the braces had been empty, then hitting @key{RET} would have put the point inside them, ready to type in the argument to @samp{\cite}. @end itemize To insert a newline, use @kbd{M-@key{RET}}. @key{LFD} ends a paragraph when that makes sense, and checks the paragraph to see if parentheses, etc., are properly matched. @comment --------------------------------------------------------- @node Fonts, Greek keyboards, Smart return key, Features @comment node-name, next, previous, up @section Fonts @findex ultex-font @cindex Fonts @cindex @TeX{} Fonts In a typical @TeX{} document, one might use a number of different type faces---bold-face, italics, small caps, whatever. Ultra-@TeX{} provides an easy way to insert the command to change type faces. Here is a typical example: hitting @kbd{M-E} inserts the string @samp{\emph@{@}}, and puts the point inside the braces. (Note: that key sequence is @kbd{@key{META}-@key{SFT}-e}, not @kbd{@key{META}-e}). The @key{META} key, in combination with various other capital letters, produces similar effects: @itemize @bullet @item @kbd{M-A} inserts @samp{\mathcal@{@}}; it also beeps if you're not in a math environment. @item @kbd{M-B} inserts @samp{\textbf@{@}} or @samp{\mathbf@{@}}, depending on the context. @item @kbd{M-C} inserts @samp{\textsc@{@}} or @samp{\mathsc@{@}}. @item @kbd{M-E} inserts @samp{\emph@{@}}. @item @kbd{M-F} inserts @samp{\textsf@{@}} or @samp{\mathsf@{@}}. @item @kbd{M-I} inserts @samp{\textit@{@}} or @samp{\mathit@{@}}. @item @kbd{M-M} inserts @samp{\mit@{@}}. @item @kbd{M-R} inserts @samp{\textrm@{@}} or @samp{\mathrm@{@}}. @item @kbd{M-S} inserts @samp{\textsl@{@}} or @samp{\mathsl@{@}}. @item @kbd{M-T} inserts @samp{\texttt@{@}} or @samp{\mathtt@{@}}. @item @kbd{M-U} inserts @samp{\textup@{@}}. @item @kbd{M-X} inserts @samp{\text@{@}}; it beeps if you're not in a math environment. @item @kbd{M-Z} inserts @samp{\zz@{@}} (intended to be a user-defined font). @end itemize These keys all call the function @code{ultex-font}, with an appropriate argument. This wasn't written with customization in mind, but if you want to modify things, you can try adding lines like this to your @file{.emacs} file (@pxref{.ultex file}): @example (define-key ultra-tex-mode-map "\C-[D" '(lambda nil (interactive) (ultex-font "bozo"))) @end example and see what happens when you hit @kbd{M-D}, both in and out of a math environment. If things don't work the way you want, you may have to modify the definition of the function @code{ultex-font}. @comment --------------------------------------------------------- @node Greek keyboards, Everything else, Fonts, Features @comment node-name, next, previous, up @section Greek keyboards @vindex ultex-greek-keys-file @findex ultex-redefine-greek-key @cindex Greek keyboards @cindex Keyboards @cindex alpha, beta, ... @cindex Greek keys file The user's textree file (@pxref{Making a list}) stores a lot of her favorite @TeX{} commands, and hitting the @kbd{$} key (@pxref{Dollar signs}) produces some other useful commands. There is a third way to insert @TeX{} commands---via a @dfn{Greek keyboard}. If you hit the left quote key @kbd{`} followed by @kbd{a}, then @samp{\alpha} is inserted into the buffer (and you get an error if you're not in a math environment). Similarly, @kbd{`b} gives you @samp{\beta}, etc. Furthermore, while hitting @kbd{`g} gives @samp{\gamma}, hitting @kbd{`G} gives @samp{\Gamma}. Once you hit the @kbd{`} key, you can access the (ordinary) Greek keyboard, the Shift Greek keyboard, the Control Greek keyboard, the Meta, the Meta Shift, and the Meta Control Greek keyboards. This gives you a lot of slots for storing @TeX{} commands. In order to see what symbols are stored in these slots, you can use the @kbd{\} key: hitting @kbd{`\} opens up a little window which displays a chart with the typewriter keys and their effect in the Greek keyboard---it might look something like this: @example times amalg oplus otime odot wedge vee sqcup cap cup uplus pm circ 1 2 3 4 5 6 7 8 9 0 - = ` theta infty varep rho tau upsil xi iota omega pi subse supse q w e r t y u i o p [ ] alpha sigma delta varph gamma eta exist kappa lambd int in a s d f g h j k l ; ' zeta chi psi foral beta nu mu sum prod not z x c v b n m , . / @end example (Unfortunately, it only has room to display the first five characters of the @TeX{} command.) In this example, hitting @kbd{`,} would produce @samp{\sum}, hitting @kbd{`6} would produce @samp{\wedge}, hitting @kbd{`e} would produce @samp{\varepsilon}. Similarly, hitting @kbd{`|} gives you the Shift Greek keyboard, @kbd{`C-\} gives the Control Greek keyboard, etc. The bindings for the Greek keyboards are stored in a @dfn{greek-keys} file. Remarks: @enumerate @item A sample greek-keys file, @file{greek.el}, is included in the Ultra-@TeX{} package. @item The path name of this file is stored in the variable @code{ultex-greek-keys-file}. @xref{Installation}, for how to set this, if you're not sure. @item If you're in Ultra-@TeX{} mode, you can run the command @code{ultex-redefine-greek-key} to change one of the Greek key bindings (just follow the directions). (Alternatively, the greek-keys file is an Emacs lisp file, so you can edit it directly if you're comfortable with Emacs lisp.) Note: you will get an error if you use any Greek key if you're not in a math environment, so you probably only want to bind math symbols to Greek keys. (The appropriate string will be inserted in any case, though.) @end enumerate @comment --------------------------------------------------------- @node Everything else, , Greek keyboards, Features @comment node-name, next, previous, up @section Everything else @vindex ultex-latex-skel-file @vindex ultex-skel-hook @vindex ultex-match-braces @vindex ultex-match-brackets @vindex ultex-match-parens @vindex ultex-array-environs @cindex Miscellany @cindex Braces @cindex Matching braces @cindex Brackets @cindex Matching brackets @cindex Parentheses @cindex Matching parentheses @cindex Quotation marks @cindex Superscripts @cindex Subscripts @cindex TAB key @cindex Double backslash @cindex \\ There are a number of other features. I'll probably forget one or two, but here are most of them: @itemize @bullet @item Hitting @kbd{C-c C-s} inserts a template for a La@TeX{} document. This template is stored in a file; its pathname is given by @code{ultex-latex-skel-file}. A sample file is included in the package: @file{skeleton.tex}. (Also, once the template is inserted, Emacs runs @code{ultex-skel-hook}.) @item Hitting @kbd{@{} makes a brace pair and puts the point inside. If you want similar behavior for @kbd{[} and @kbd{(}, then customize the variables @code{ultex-match-brackets} and @code{ultex-match-parens}. On the other hand, if you don't want this behavior for @kbd{@{}, then customize @code{ultex-match-braces}. @item Hitting the double-quote key @kbd{"} makes either two left single quotes @samp{``} or two right single quotes @samp{''}, whichever Emacs thinks is appropriate. @item Hitting @kbd{...} inserts @samp{\dots}. (It used to insert @samp{\cdots} or @samp{\ldots}, depending on what it thought was appropriate, but I believe that the recent versions of La@TeX{} will position @samp{\dots} according to the context.) @item Hitting @kbd{^} produces @samp{^@{@}}, with the point inside the braces. Hitting @kbd{_} produces @samp{_@{@}}, with the point inside the braces. @item Hitting @key{TAB} in an array environment moves the point forward a few spaces, and inserts @samp{&}. (Emacs determines when to do this by using the variable @code{ultex-array-environs}, which is a list consisting of environments that use @samp{&} for ``tab stops''.

That tells you how to byte-compile the Emacs lisp code and how to produce the documentation in various formats. It also has basic instructions for how to modify your @file{.emacs} file. Here are more details about @file{.emacs}: @itemize @bullet @item Make sure the directory @file{ultratex-0.50/lisp} is in your load path. It might be good to make a symbolic link from @file{ultratex-0.50} to @file{ultratex} and then put @file{ultratex/lisp} in your load-path, so that if this package ever gets upgraded to @file{ultratex-0.51} and you choose to install it, you only have to change the symbolic link, not your @file{.emacs} file. For example, I have the following line in my @file{.emacs} file. @example (setq load-path (cons "/home/palmieri/emacs/ultratex/lisp" load-path)) @end example @item Put the files @file{textree.el}, @file{greek.el}, and @file{skeleton.tex} someplace. They start in the directory @file{ultratex/user}, but if you change them from their defaults, you might want to move them elsewhere so they don't get overwritten when you install a new version of the Ultra-@TeX{} package. @item Put the following line in your @file{.emacs} file: @example (require 'ultex-setup) @end example @end itemize Now the next time you start Emacs, whenever you find a @TeX{} file, you will automatically be put into Ultra-@TeX{} mode. @comment --------------------------------------------------------- @node .ultex file, Customization variables, Basic installation, Installation @comment node-name, next, previous, up @section .ultex file @vindex ultex-init-file @cindex .ultex file @cindex Ultra-@TeX{} init file When Ultra-@TeX{} starts up, it loads the file @file{.ultex}. This was useful in versions of Ultra-@TeX{} before 0.50, when one would set many options by hand and then wanted to avoid cluttering up the @file{.emacs} file with various Ultra-@TeX{} settings. This is not so useful in version 0.50 (or later) of the Ultra-@TeX{} package, since all of the features can be customized, and the customizations get stored in @file{.emacs} automatically. The name of the @file{.ultex} file is given by the variable @code{ultex-init-file}, so if you'd rather give this file a different name, like @file{.ultra-tex-stuff.el}, then customize this variable accordingly. @comment --------------------------------------------------------- @node Customization variables, , .ultex file, Installation @comment node-name, next, previous, up @section Customization variables @cindex Customization @cindex Groups, customization @cindex Customizable options @cindex List of customizable options @cindex Options Many of the features of Ultra-@TeX{} mode are customizable.

This is pretty, but it can add a noticeable delay when starting Ultra-@TeX{} mode. @item ultex-use-font-latex Default value: nil. Effect: Toggle use of the @code{font-latex} package for colorization. This variable is only relevant if @code{ultex-use-color} is @samp{on}. One version of the file @file{font-latex.el} is distributed with Ultra-@TeX{}. The most recent version is available from @url{ftp://ftp.phys.ocean.dal.ca/users/rhogee/elisp/font-latex.el} @item ultex-use-auctex Default value: nil. Effect: Toggle use of files from AUC-@TeX{} distribution. This has one main effect: several commands are added to Ultra-@TeX{} to allow one to typeset the current @TeX{} document, spawn an external viewer, jump to the next error, etc. This option requires the use of the file @file{tex-buf.el} from the AUC-@TeX{} distribution. This file is included with Ultra-@TeX{}, but if you want the most up-to-date version, the AUC-@TeX{} package is available from @url{http://sunsite.auc.dk/auctex/}. @xref{ultra-tex-auctex}, for options related to this one. @item ultex-use-imenu Default value: nil. Effect: Toggle use of @code{imenu} package in Ultra-@TeX{} mode. The @samp{imenu} package lets you pop up a menu giving an outline of the buffer, so that you can move around to various section headings and theorem statements and so forth. If this option is on, then S-mouse-3 (hold down the shift key, and hit (and release) the right mouse button) runs the command @code{imenu}, which pops up the aforementioned menu. @item ultex-use-bib-cite Default value: nil. Effect: Toggle use of @code{bib-cite} package in Ultra-@TeX{} mode. The @code{bib-cite} package does stuff with your labels and citations -- highlights them, lets you jump to them, etc. This option is not well-tested, and may yield unpredictable results.
