[GRASS-dev] Discussing new GUI toolkit: v.pydigit

[William Kyngesburye]

Ooh - xev tells me that the two-fingered right-click indeed does  
'button 3' in X11.  Another interesting thing: another two-fingered  
trick is scrolling, which seems to work also, giving buttons 4 & 5 in  
X11, the scroll-wheel I presume.

With the emulate 3 button mouse option on in X11, it's apple-click  
for right-click (and option for middle).  These also show the correct  
button click in xev, but the apple/option keys precede that, which  
might confuse some X11 programs (not GRASS).
