I don't know if this would be easy to change, its coded in an unintuitive way (IMHO). I need to look at the code more to see if there's an easy solution. Assuming that nobody wants to keep the current behavior. :-) 

Would be awesome if you could figure that one out.
It should actually be doable without too much work. What are the votes on "zoom-to-center" and "zoom-to-mouse"? 


MMB already performs moving - but I only realized after posting the patch
LMB selects a region
RMB over an unselected region puts up a menu
RMB over a selected region allows moving the region

I'd actually leave the mouse buttons as they are to leave RMB for menus,
and just change the mousewheel default behavior to zoom. Scrolling by wheel could be removed, or made secondary behavior of the mousewheel when modifier keys are held down. 

Sounds good.
Okay, then I'll implement it this way. However, which modifier keys for moving? As I regard Shift as the primary modifier, I'd set this for vertical scrolling, and Control and Command for horizontal. 

And some more keyboard navigation issues:
I'd like to have <PageDown> and <PageUp> for Next/Previous image; many viewers on Windows work that way, and I've gotten very used to it. This allows one-handed navigation, which isn't doable with the current <Alt>+<Down>/<Up>. 
The code change is trivial, already implemented in my version.
Likewise, <Home> and <End> for jumping to first and last image would be nice. <Home> would be trivial as well, but <End> would need some work in the file routines. 

Any votes/vetoes on this?
