For one, Mozilla doesn't use Motif. Can't speak for Opera.

Thanks for the comments. Mouse gestures will be a preference, which is off 
by default. 

Some people commented about the 'rocker' gesture - a different type of 
gesture where one presses the primary mouse button then presses the 
secondary mouse button (or visa versa) in a 'rocking' motion, usually 
assigned to backward and forward navigation (but should probably be user 
definable). 

I didn't add this feature yet because I wanted to first discuss the 
implications of sharing the primary (usually left) mouse button with the 
editor developers (like Kai, specifically). Getting the secondary button 
seems fairly non-invasive so far, with the exception of this context menu 
issue on Motif, but for the rocker gesture you can't really have one 
direction without the other and until the implications of sharing the 
primary button are understood, rocker gestures should remain out. 

Regarding Motif, I suppose a preference to enable mouse gestures (meaning 
the user has to 'sign up' for the change in behavior) won't be sufficient 
for hardcode Motif users. I'm not sure how Opera/Mozilla solve this issue 
on Motif, if at all. Could someone investigate this? Another option I have 
is allowing the user to specify that one or more modifier keys (Ctrl, Alt, 
Shift, Command) must be pressed to enable gesture recognition. This should 
solve the problem on Motif, but unfortunately will make the feature 
somewhat less useful. Mozilla supports modifier keys as a preference. 

Chris.
