The back of my mind tapped me on the shoulder and whispered ".nop";
but there's no such thing. Then I grepped .../tmac/* and caught the
following in tmac.s:

  .de @nop
  ..

which is for "private" use when a survivable error is found in
a macro, which then gets aliased to @nop as in

  .de @not-implemented
  address@hidden sorry, \\$0 not implemented
  .als \\$0 @nop
  ..

However, it's available for public use as well ...

Yes: In 'man troff', section "New requests".

Cheers,
Ted.
