Comment(by cmbarton):

 I've had a report from a student that the Windows version of GRASS 6.4 is
 also having confusion with the right and middle click. A standard way to
 fix this could be the following:

 1. add an alternate binding of a double left-click to end a line or close
 a polygon (this is standard on most graphics programs Mac and Windows, and
 even shows up on Linux). The same could be used to quit a tool.

 2. for anything else that requires a right-click (e.g., a contextual
 menu), provide an alternate binding for a key combination (it would be
 Ctrl + left-click on the Mac; I'm not sure on Windows)

 3. for anything that requires a middle-click, provide an alternate binding
 for a key combination (option + left-click for Mac and perhaps alt + left-
 click for Windows). For zooming, a one left-click zoom-in, like the zoom-
 out would make zooming usable even without a middle button. Using the
 middle-button for marking a zoom box corner is not needed since the TclTk
 canvas supports rubber-band boxes. But this would require some
 reprogramming. At a minimum, binding the box end to option-click (Mac)
 and/or alt-click (Windows) would make this functional.
