You wish but did you try anything?

Look for something called "global keyboard and mouse hooks". These are a set of API which allows you to trigger events when the user moves the mouse or uses the keyboard. There are plenty of articles written about it in CodeProject itself.

Hope this helps :)

Keyboard hooking is the answer you're looking for.
You'll have to interact with a Windows DLL for that, but there are plenty of good articles on it on codeproject.
Try this Global Mouse and Keyboard Library[^].
I believe it contains all you need.
