Custom Keybindings Were a Developer Plan, Not a Demo Menu

Underkeep custom keybindings were explicitly discussed as a planned feature after players asked for remapping. In a March 1 developer reply, keyboard-and-mouse controls were described as functional in the demo, but the demo did not have a dedicated screen clearly listing them. A March 6 reply then said keyboard and gamepad controls were intended to become fully customizable.

Those statements answer an important question if you are searching the old demo for a remapping menu: the discussion does not establish that such a menu had shipped. It also does not provide a supported configuration-file path or a step-by-step remapping procedure.

See the developer replies in What Are the PC Controls?.

Distinguish Keyboard-and-Mouse From Keyboard-Only Play

Working keyboard controls do not necessarily mean every interaction can be completed without a mouse. In June feedback, a player reported being unable to find a keyboard confirmation option and still needing the mouse for dialogue choices, loot pickup, and inventory management.

The developer responded that keyboard-only controls were planned, while explaining that distinguishing keyboard-only play from keyboard-and-mouse use introduced interface complications. That reply supports the planned direction, not a claim that a complete keyboard-only scheme already existed in the public demo.

The official Underkeep website advertises mouse-and-keyboard play and controller support. It does not, by itself, document every remapping option or every keyboard-only interaction.

Check Your Version Before Editing Configuration

One player's mention of a game_config file is not enough to establish a safe universal editing guide. The discussion does not supply a verified location, complete binding syntax, or a working confirmation binding to copy.

Before treating a requested feature as an available setting:

  • Check the controls and options actually present in your version.
  • Keep the March demo limitations separate from the developer's future customization plan.
  • Use the mouse for interactions that your demo does not expose through a working keyboard command.
  • Consult newer official instructions if your build includes features absent from the older discussion.

Do not assume that changing movement keys will also add keyboard support for dialogue and inventory. Those are different parts of the control scheme.

FAQ

Did the developer promise customizable keyboard controls?

The March 6 reply states that keyboard controls would be fully customizable. It is a development plan rather than proof of availability in the cited demo.

Why can I not find a controls screen in the demo?

The March 1 developer reply says the demo lacked a dedicated screen clearly listing the controls, even though keyboard-and-mouse input worked.

Is there a verified configuration-file fix for keyboard-only play?

Not in these developer replies. A player mentions searching game_config, but no confirmed path and complete working procedure are provided.
