When playing on a computer, you can open the In-Game Console Options using a keyboard shortcut at any time while a game is running.
Press Shift + F12 to open or close it.
On laptops or keyboards without dedicated function keys
On many Mac and some Windows laptops, function keys (F1–F12) act as media or system keys by default and require the Fn key to be held. In this case, use:
Shift + Fn + F12
If you are unsure whether your keyboard requires Fn, try Shift + F12 first. If nothing happens, try Shift + Fn + F12.
