%\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.
