More options for hotkeys

I really, really, love Across. It works nearly flawlessly. I would just really like more options for hotkeys to switch devices.

For example I would like to map switch devices to "Right-Windows" key. I don't use this key for anything else and it would be perfect.

Or some other combination like "Control+Middle Mouse".

Just more options like other software.

 

Thanks for the suggestion. Are you using both the keyboard and mouse hotkeys?

 

I do use both right now, but I primarily use the mouse. My mouse (Microsoft sculpt mouse) has a strange Windows button on it that registers as a Right-Windows Key press. I would like to use that to switch instead of the 3rd mouse button.
