just an idea:
shift+mousewheel could be used to scroll horizontal in the PB-IDE.
or is there already another way than to use the scrollbar? something like
vertical scrolling with cntrl+up/down, but for horizontal ?
i actually meant the cntrl+up/down for the cursor keys as is already works, no mouse. it was just to show what i mean, and to ask if there's already a way like this but for horizontal scrolling (left/right).
your idea with the middle mousebutton is good too. i used the all-direction-scrolling with middle mousebutton once in a program i wrote and it's indeed a very nice handling in general, but i think the shift+mousewheel would be much easier to implement.
