Most KVM switches have a keyboard shortcut (mine is scroll lock, scroll lock, 1/2). Mine also supports the mouse based switching but it's unusable because to work it needs to emulate a mouse with zero acceleration. Also this doesn't switch video.

I've had the same idea tbh but the inability to switch video and the software complexity put me off. A KVM switch is better (except the cost).
