Hello

I did'nt find anything in search results about that:

If assigning the hot key Ctrl + Q , I get it

But nothing If assigning F12

I suppose there is a thoroughly simple explanation

Thanks

F12 is reserved by the system debugger. As it is already in use you cannot reassign it.

"The F12 key is reserved for use by the debugger at all times, so it should not be registered as a hot key. Even when you are not debugging an application, F12 is reserved in case a kernel-mode debugger or a just-in-time debugger is resident."

Thanks Marcus for this quick advice

...but why does F12 appear in the hot key list ?

Because it is possible to turn off the system debugger, not all systems may have it, some people might remap system keys .....

Many of the F keys are already in use - e.g. F1 does windows help and help in most other apps, F5 is refresh etc.

It is not really practicable for us to determine whether they are in use or not by other processes. So all are offered for use. It's up to you how you use your keyboard.
