These keys do not work in any gmod server, they instead do the functions printed on them, is there any way to disable the special part of the function and just leave it a function key?
Is this on a laptop? I’ve seen cases where the F key functionality can be changed in the BIOS but it could also easily be a program. Try looking up how to change the functionality for your device.
It is a laptop, yes.
Do you have a Fn Lock key? It’s for the extra functions on those keys.
