The name of the counter is the same as the name of the environment or command that produces the number, except with no \. (enumi - enumiv are used for the nested enumerate environment.) Below is a list of the counters used in LaTeX's standard document classes to control numbering. part paragraph figure enumi chapter subparagraph table enumii section page footnote enumiii subsection equation mpfootnote enumiv subsubsection \addtocounter: Add a quantity to a counter. \alph: Print value of a counter using letters. \arabic: Print value of a counter using numerals. \fnsymbol: Print value of a counter using symbols. \newcounter: Define a new counter. \refstepcounter: Add to counter, resetting subsidiary counters. \roman: Print value of a counter using roman numerals. \setcounter: Set the value of a counter. \stepcounter: Add to counter, resetting subsidiary counters. \usecounter: Use a specified counter in a list environment. \value: Use the value of a counter in an expression. ############################################################ \addtocounter ::addtocounter:: ############################################################ \addtocounter{counter}{value} The \addtocounter command increments the counter by the amount specified by the value argument. The value argument can be negative. ############################################################ \alph ::alph:: ############################################################ \alph{counter} This command causes the value of the counter to be printed in alphabetic characters. The \alph command uses lower case alphabetic alphabetic characters, i.e., a, b, c... while the \Alph command uses upper case alphabetic characters, i.e., A, B, C.... ############################################################ \arabic ::arabic:: ############################################################ \arabic{counter} The \arabic command causes the value of the counter to be printed in Arabic numbers, i.e., 3. ############################################################ \fnsymbol ::fnsymbol:: ############################################################ \fnsymbol{counter} The \fnsymbol command causes the value of the counter to be printed in a specific sequence of nine symbols that can be used for numbering footnotes. eg. From 1-9: NB. counter must have a value between 1 and 9 inclusive. ############################################################ \newcounter ::newcounter:: ############################################################ \newcounter{foo}[counter] The \newcounter command defines a new counter named foo. The counter is initialized to zero. The optional argument [counter] causes the counter foo to be reset whenever the counter named in the optional argument is incremented. ############################################################ \refstepcounter ::refstepcounter:: ############################################################ \refstepcounter{counter} The \refstepcounter command works like \stepcounter See section \stepcounter, except it also defines the current \ref value to be the result of \thecounter. ############################################################ \roman ::roman ############################################################ \roman{counter} This command causes the value of the counter to be printed in Roman numerals. The \roman command uses lower case Roman numerals, i.e., i, ii, iii..., while the \Roman command uses upper case Roman numerals, i.e., I, II, III.... ############################################################ \stepcounter ::stepcounter:: ############################################################ \stepcounter{counter} The \stepcounter command adds one to the counter and resets all subsidiary counters. ############################################################ \setcounter ::setcounter:: ############################################################ \setcounter{counter}{value} The \setcounter command sets the value of the counter to that specified by the value argument. ############################################################ \usecounter ::usecounter:: ############################################################ \usecounter{counter} The \usecounter command is used in the second argument of the list environment to allow the counter specified to be used to number the list items. ############################################################ \value ::value:: ############################################################ \value{counter} The \value command produces the value of the counter named in the mandatory argument. It can be used where LaTeX expects an integer or number, such as the second argument of a \setcounter or \addtocounter command, or in: \hspace{\value{foo}\parindent} It is useful for doing arithmetic with counters. @
