Well, one online map application here in Czech republic [1] uses left 
mouse button for dragging/panning actual view while Ctrl+mouse is used 
for selecting an area to zoom in.

I choose Ctrl for panning because I didn't want to break compatibility 
with existing KPA.

The patch hasn't been applied yet so feel free to change it as long as 
you provide a workaround for people who can't use middle button (and no, 
  3rd button emulation won't help in this case because of wheel emulation).

Also note that while in the fullscreen view, left button is used for 
zooming, but you use the middle one for that in the thumbnail view.
