Menu that pops up when you press the key "C"

Garry's Mod help & support
#1

For some reason I cannot use the “C” key to open up the menu thing, I think its just a garry’s mod error since I can use the “C” key here but not on servers on garry’s mod, so I’m asking what do I do to solve this

#2

Open console and run


bind c +menu_context
