From Garry's Mod
Runs when a IN key was released by a player.
|NOTE||This hook is predicted. This means that in singleplayer, it will not be called in the Client realm.|
"hi" will be printed to the console when the player releases the IN_USE (E) key.
function GM:KeyRelease( player, key ) if ( key == IN_USE ) then print( "hi" ) end end
