Laptop Optimization

I installed GW on the laptop for portability over the holidays and am having some challenges optimizing the interface for use on a laptop. In addition to the various hotkeys and controls, I have a specific issue I wonder if anyone has found a solution for.

Specifically, is there a way to map the camera zoom in/out to keystrokes rather than to the mouse wheel? Right now the only way I can get the functionality on the laptop is by simultaneously clicking both buttons on the touchpad and dragging the camera in or out. Very bad stuff. Mapping zoom in to > and zoom out to < would be much better. Does anyone know if there's a way to do this?

I know this doesn't help you now, but I use a mouse with my laptop - makes all gaming easier.

That would be ideal, but if no mouse is available, is there a way to map hotkeys for zoom in/zoom out?

I'm not sure. You might be better off just spending a little on a mini-mouse. You can get them pretty cheap. I started off just trying to use the touch pad on my laptop, its comparably *very* awkward.
