I would really like "up" to be jump for this game, especially since it doesn't seem to serve any other purpose, but there doesn't seem to be an option to bind keys in this game.
Is there any way to bind keys for Starbound, or otherwise change the input options for the game?
Update: Upbeat Giraffe
The Upbeat Giraffe update has added keybindings to the game. Please update your answers accordingly, and thank you for your answers from when this game did not have such a feature.
