I'm trying to map View.NavigateBackward and View.NavigateBackward like so:

• View.NavigateBackward = Alt + LeftArrow
• View.NavigateForward = Alt + RightArrow

Pretty simple to do in Visual Studio with the Keyboard Options dialog. OK so I've assigned the shortcuts and the NavigateBackward one is working. But NavigateForward, which used to be assigned to Edit.CompleteWord, is staying with its old assignment. I've checked that Edit.CompleteWord is assigned to 'Ctrl+K, W' but the Alt+RightArrow is still behaving as complete word. Is there something special about the arrow keys that I can't assign them?

I want to do this so the mouse buttons behave the same in VS 2010 and my web browser. Works fine for the back button, but the forward button won't re-assign properly. Suggestions?
