Slightly.

The main problem is ctrl- and shift- are already taken up as click 
modifiers that give different behavior.  So we shouldn't use those to 
simulate a different button.  Another problem is various systems may 
already make use of one of the modifier buttons.  For instance X11 
window managers usually overload alt- and it sounds like mac native 
overloads ctrl-click.

However it sounds like mac has two additional buttons, command- and 
option-.  In GTK the modifiers aren't named; they're just MODIFIER1, 
MODIFIER2, MODIFIER3, etc.  MODIFIER1 is usually alt and this is what we 
use to simulate middle-click.  On macintosh I guess MODIFIER2 also 
exists.  The modifier buttons go up pretty high; I don't know how 
they're configured on different systems.

 From what you say it seems we don't have to worry about simulating 
3-buttons on mac X11, since X does this for us.  We do have to worry 
about it for mac native, except that GTK doesn't run in mac native yet 
(but this is only a matter of time).

So I guess this means the best choice is just to use 
MODIFIER2-left-click to simulate right-click.
