You can play Among Us on PC with keyboard control settings. Although you currently cannot change the key bindings there’s a set number of keys you can use to play the game.

Keyboard Settings

First, in the settings menu ensure that under “Controls” you have “Mouse+Keyboard” selected.

Once enabled you will be able to use the following shortcuts:

E or SpaceUse
Sabotage (As Imposter)
QKill (As Imposter)
RReport Body
TabOpen Map

Just be careful with the “E” use key as Imposter. It’s used for both venting and bringing up the sabotage map.
