this, Emacs chooses the mode specified by the variable
@code{tex-default-mode}; its default value is @code{latex-mode}. If
Emacs does not guess right, you can select the correct variant of
-@TeX{} mode using the command @kbd{M-x plain-tex-mode}, @kbd{M-x
-latex-mode}, @kbd{M-x slitex-mode}, or @kbd{doctex-mode}.
+@TeX{} mode using the commands @code{plain-tex-mode},
+@code{latex-mode}, @code{slitex-mode}, or @code{doctex-mode}.
The following sections document the features of @TeX{} mode and its
variants. There are several other @TeX{}-related Emacs packages,
@kindex C-c C-v @r{(SGML mode)}
@findex sgml-validate
Run a shell command (which you must specify) to validate the current
-buffer as SGML (@code{sgml-validate}).
+buffer as SGML (@code{sgml-validate}). (In HTML mode this key
+sequence runs a different command.)
@item C-c @key{TAB}
@kindex C-c TAB @r{(SGML mode)}
