If you have any free tap gestures, you could set one up. I use some of the blank keys for that with macros instead of even having a gesture, it's just like a single keypress. The blank keys I am referring to are 3 keys left of F4,F5,F6, 1 key below F6 above Backspace, 1 key below F12 above Space, 3 keys right of F10,F11,F12, and 1 key left of the up arrow. I actually have Enter assigned left of the up arrow and could technically use the enter key for something else. The rest of the keys I just mentioned all have macros assigned for various keyboard shortcut functions.
