[UI] Mouse vs Keyboard

[Bert Freudenberg]

Actually it is because the VM format of mouse events assumes only 3  
mouse buttons (it reserves 3 bits). Adding a special keyboard event  
was simpler (I confess to being guilty of this).

It doesn't really matter what the OS sends (on Unix it is a click of  
mouse buttons 4 and 5, on Windows it is a special "scroll" event IIRC).

The Right Thing to do would probably adding a new type of event to  
the VM, which might also include horizontal scrolling somehow (the  
easier thing being adding ctrl-left/right ;)
