HotKeys, Zoom etc, etc

[Captfinn]

I just installed MC. I know I can scale and resize an object. However, i don't want to resize and scale. I simply want to zoom in and out.
How do you zoom in and out within MC? I'm sure a scroll wheel is a default method. I however use a Logitech Marble Mouse. No scroll wheel.

Also, where can I find the hotkeys for things like the redo and undo buttons, etc.

Holding the Control (Ctrl) button on your keyboard, tap the "-" or "+" keys to zoom in and out.
