%\description
% \var{html_mode} is a mode designed for editing HTML files.
% If a region is defined (i.e., if a mark is set), many HTML
% tags will insert around the region, e.g. '<B>' and '</B>'.
%
% Keybindings begin with ^C and are grouped according to function:
% ^CA... Anchors (<A>...</A>)
% ^CD... Definition lists (<DL>...</DL>)
% ^CF... Forms (<form>...</form>)
% ^CH... Headings, document type, etc.
% ^CI... Images
% ^CL... Lists (<UL>...</UL>)
% ^CP... Paragraph styles, etc. (<P>, <BR>, <HR>, <ADDRESS>, etc.)
% ^CS... Character styles (<EM>, <STRONG>, <B>, <I>, etc.)
% ^CT... Tables
% Additionally, some special movement commands and miscellaneous
% characters are defined:
% ^C^B skip to beginning of prior HTML tag
% ^C^F skip to end of next HTML tag
% ^C^N mark next HTML tag from '<' to '>'
% ^C^P mark prior HTML tag from '<' to '>'
% ^C& insert HTML text for '&'
% ^C> insert HTML text for '>'
% ^C< insert HMTL text for '<'
% ^C<enter> insert HMTL text for '<br>'
% ^C<space> insert HMTL text for NonBreakableSPace
% ^Ce insert HMTL text for 'Eurosymbol'
% ^CC insert HTML comment (around region, if marked)
%
% For a complete list of keybindings, use \var{describe_bindings}.
%
% This function calls \var{html_mode_hook} if it exists.
