Keyboard Shortcut to Swap Mouse Buttons

Question

I use my mouse with both hands and like to switch back and forth for comfort reasons. However, this is made difficult by needing to go through about a zillion layers of menus to swap the buttons each time. Is there an easy way to create a single keyboard shortcut that would swap my left and right mouse button?

Edit: My OS is Windows 7.

Answer 1

I dunno about a keyboard shortcut but you can make two reg files that do what's described here. Just click and away you go.

If you really want to get nuts with it, set up an AutoHotkey script that triggers the reg files
