# Keyboard Controls

For faster operation of the Antikythera you can use key commands.

Notes:

- There is a timeout between the first and second key of a multi-key command:
  If you are too slow the command is ignored.
- You can use lower case, upper case or a mix: YAAS is not case sensitive
- Keys that operate like a button are underlined on the control panel
