Return of Reckoning

Greetings All!

I'm a long-time user of a Logitech Trackball mouse, which lacks a mouse wheel.
I'd like to zoom out just a bit on my toon, but I can't seem to find any information on key strokes that would allow me to do that?
Any thoughts?

Well, if there is no particular setting in the key mapping of ROR you could alternatively use a keymapping tool like Autohotkey to remap the mousewheel actions to any keybinding of your choice.
