How do you open the inventory menu in Undertale?

3 Answers

While playing Undertale, you'll want to use C or Ctrl to open your menu and Z or Enter to select Inventory.

When you start up the game, the title screen features an option menu where you can reconfigure your keys. (or test the game with a joystick/gamepad if you want to use something other than a keyboard.)

In your case, it sounds like the controls might have been reconfigured at some point.

Also, if you are playing on Switch, hit "X."

You just press C, but if you play one-handed, then you can use ctrl. But when you start the game, you can change this is you want to.
