T.9.2 LaTeX Editing Commands

LaTeX mode, and its variant, SliTeX mode, provide a few extra features not applicable to plain TeX.

C-c C-o

Insert `\begin' and `\end' for LaTeX block and position point on a line between them (tex-latex-block).

C-c C-e

Close the innermost LaTeX block not yet closed (tex-close-latex-block).

In LaTeX input, `\begin' and `\end' commands are used to group blocks of text. To insert a `\begin' and a matching `\end' (on a new line following the `\begin'), use C-c C-o (tex-latex-block). A blank line is inserted between the two, and point is left there. You can use completion when you enter the block type; to specify additional block type names beyond the standard list, set the variable latex-block-names. For example, here's how to add `theorem', `corollary', and `proof':

(setq latex-block-names '("theorem" "corollary" "proof"))

In LaTeX input, `\begin' and `\end' commands must balance. You can use C-c C-e (tex-close-latex-block) to insert automatically a matching `\end' to match the last unmatched `\begin'. It indents the `\end' to match the corresponding `\begin'. It inserts a newline after `\end' if point is at the beginning of a line.
