my (very) old binds !
These binds are not useful for this server , I used them long time ago , but you would understand how it works by looking at these examples
Note:
>>> Sleep <<<means waiting for a couple of milliseconds (each second is 1000 ms)
>>> Numpad1:: <<< this defines the key being used for the bind and the :: means the action will be excuted whenever you press it and if you use # at first of it means you have to hold it
>> SendInput << This is the sentence it sends after you press a certain keybind
