MadMonkey: There are two ways for my device: First, there is a button on the front which cycles through the plugged computers, or I can use a keyboard shortcut (It's two time scroll lock [have you ever used that key?]) for that. It then gives you an accustic feedback. I think every KVM switch has these two ways of switching, just the shortcuts may vary, Ctrl+NumLock is often used I think. Of course, I never use the button on the device's front, it's just too much movement ;-) And with the keyboard shortcut I can put the switch under the desk so it doesn't even get into my way.

I love this thing
