The easiest way would probably be to add new page actions (Setup -> Actions) - have them parse markup_help_font.html, for example, and markup_help_icons.html. Then copy over markup_help.html to those two template. Inside the <%loop markup_loop%> of each page, add:

<%if type ne 'xyz'%><%nextloop%><%endif%>

'xyz' should be one of the text strings for the markup tags, as defined in the admin panel (i.e. 'Font Color', 'Font Attribute', 'Emotion Icon', etc.). If you wanted to combine a few on a page, you would use:

<%if type ne 'xyz' and type ne 'zyx'%>
