In Settings > Control switching based on mouse movement... > "Unless shift is held down" is there any way to change that hotkey to some other key, such as caps lock, INS, or at least a specific shift key (eg: only right shift)?

I use shift for something else in a fullscreen game that I play, and I don't want to accidentally switch computers vis Seamless. For now I'm relying on "When a fullscreen application is running" but in order to switch to my other pc, I have to either alt-tab or hit the windows key to break out of the game and back into Windows... which is not ideal.

Thanks!
