Caffeine suggestion

Instead of simulating a keypress every minute.  Let it only become active if the PC is not active for certain amount of time, like how power saving mode works.

To elaborate.  Let's say you set it as 10 minutes.  Everytime your keyboard/mouse is active, it resets the 10 minute countdown.  If keyboard/mouse is inactive, it starts the countdown.  After 10 minutes, it would start simulating the keypress every minute.

This way, while you're using on the PC, the keypress won't interrupt you.  Also you don't need it to work since you're already at the PC.

It's a neat idea, certainly, and it's been suggested before.

The trouble with it is getting the information that the machine hasn't been used for xx minutes.  To get that, Caffeine would need to ask Windows to send it all keystrokes and mouse movements - not for recording, but instead so that it knows they're happening, and so the machine is in use.

That's going to cause all kinds of trouble with security apps, as hooking the keyboard and seeing everything that the user is typing is a security risk :/
