Since Keyboard Input is deprecated, how would you use UserInputService to see if someone has pressed /?
You can use InputBegan event.
game:GetService("UserInputService").InputBegan:connect(function(input,proc) if not proc and input.KeyCode == Enum.KeyCode.Slash then --code end end)
'proc' is a variable that prevents input from getting accessed while typing in chat and similar.
