 The `@subsection'-like Commands
 ===============================
 
   The `@unnumberedsubsec', `@appendixsubsec', and `@subheading'
 commands are, respectively, the unnumbered, appendix-like, and
 heading-like equivalents of the `@subsection' command.  (
 `@subsection' subsection.)
 
   In Info, the `@subsection'-like commands generate a title underlined
 with hyphens.  In a printed manual, an `@subheading' command produces a
 heading like that of a subsection except that it is not numbered and
 does not appear in the table of contents.  Similarly, an
 `@unnumberedsubsec' command produces an unnumbered heading like that of
 a subsection and an `@appendixsubsec' command produces a
 subsection-like heading labelled with a letter and numbers; both of
 these commands produce headings that appear in the table of contents.
