Technically not very hard (though some multi-segmented curves may be
hard to find a midpoint on), but not something there's been a call for
before.

Hotkeys are not possible with the current text input system, as there's
no separate text mode, so we always need to have the keypresses
available for text.  That will change in a later version.

What does the update command do in xfig?
