 Replying to [comment:3 kyngchaos]:
 > It looks like it's a Tcltk Aqua problem, where it sees right-click
 (however it is generated) as button 2, where it should be button 3.  When
 using a 3-button scrollwheel mouse, I find that middle and right-clicks
 are swapped.

 That still leaves us without a middle-click for trackpad users.  So maybe
 v.digit needs an alternative way to trigger a 'middle-click', or the
 action it does (like undo vertex).

 recognize right-clicks correctly (according to Michael), but does it also
 use middle-clicks for other actions, in which case it would also have the
 same missing feature problem for trackpad users.

 3-button mouse option.

 In TclTk, option-click could be bound to a middle mouse button. I'd also
 prefer to have a double left click close figures (could be a right-click
 alternative). This is more Mac-like (and maybe more Windows-like)
 behavior.
