### 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.
