I set the "Forward" thumb button to a shortcut for CTRL. When swiping to another PC, in stead of using CTRL on the keyboard, I simply use this button. It works like a charm! BUT. When I do this, when Outlook is open, it opens another Outlook, and another and so on, every time I switch between PCs. I end up closing Outlook so many times that I could just as well have used the keyboard CTRL in stead.
