WASD and ARROW KEYS - movement
E and SPACE - use, sabotage, vent
R - report a body
TAB - map
ESC - options, exit terminals
Q - kill ( if you are the imposter)

To access terminals on Mira HQ, use E or SPACE. Examples include Vitals, Security Cameras, Admin Tables, and Sensor Logs. To exit these menus, press the ESC key. These bindings can be used to open the Emergency Button, but not to press it.

You can just look at the very bottom right, to know what action you'll be doing. For impostors this will usually be sabotage, so whenever they press E or SPACE away from a terminal it will open their sabotage menu. Also, like mentioned, impostors can press E or SPACE to enter or exit vents quickly.
