I don't think it has that functionality yet, though I have to admit I might
be wrong there.

the principle would be similar to the middle mouse button emulation in other
drivers. when a press is detected, a timer is set. that timer is cancelled
by a button release but if the timer expires normally a right click/button
3 event is posted to the server.
Of course, you'd need to take some motion filtering into account to avoid
having every drag action converted into right clicks.

The main usability issue is sorting out whether to delay the original button
press until the timeout is triggered or to send the button 1 press
immediately and fake the release before posting button 3. 

My tendency is that the former is better, the latter would not allow for
right clicks without previous selection. I'd be curious what windows does in
that regard though.
