Word 2011: Keyboard shortcuts for accepting/rejecting a tracked change AND moving to the next change

Thinking outside the box:

If the only reason you want the keyboard shortcut, is to avoid your mouse, have you considered a trackpoint keyboard?

Because I had RSI in the past, trackpoint keyboards are about the only ones I can use (even at clients, I usually bring my keyboard, or work from my laptop that has such a keyboard).

The big upside of those keyboards is that you don't have to take your hand of the keyboard in order to use the mouse.
For trackpads I still need to (somehow using my thumb is far less accurate on trackpads than using my index finger, o I still need to lift my hand for pointing).

It takes a little while to get used to a trackpoint, but I can't do without them any more.
USB trackpoint keyboards work equally well on Mac and PC.

"In addition, I would like to change the shortcut in 'Mission Control' which 'Move left/right a space', but doesn't seem like I can change it."

I believe I can help answer this part.

At first I thought that a drop down would appear, but it does not. All you have to do, if you want to use keyboard shortcuts (not sure about trackpad or mouse) is hit the key once the item is selected.

Above is a screenshot of the menu with default settings.

Below is a screenshot of the menu with moving to the right changed to "."

So, to recap: Highlight item to change, double click on current shortcut symbol (to highlight it), immediately hit new key for the shortcut.

Hope this helps some!
