I see Editortoolbar is already covered.

Since this is about navigating by mouse: By default the IDE reacts to 
the 2 extra buttons of a 5 button mouse (forward/backward in history). 
Similar like some web browser do.

If you do not have a 5 button mouse you can map this to other buttons. 
(also with shift/ctrl/alt / on some OS not all modifiers work with the 
right mouse button.)
