I recently purchased a P3421W, and am enjoying it immensely.  However, I'm stumped on a specific use case scenario.  I have a personal PC and work laptop hooked up to the P3421W.  I also have a second monitor dedicated to my personal PC.

I understand that when in PbP or PiP mode, I can create a key combo to switch which system is being controlled by the kbd and mouse, without any change to video.

However, I often find myself running the P3421 as my dedicated work screen, and my personal PC on my secondary screen only.  In this case, I'd love to be able to hot switch JUST my kbd and mouse, not my video.  

I can do it in PbP mode, what about in this use case?
