Debug Toolbar
From Kerbal Space Program Wiki
Cheats alter the gameplay useful for helping debugging, simplifying missions for newbies, goofing off, or just plain cheating.
With Mod+F12 a cheat window opens with the following options:
- Hack gravity: No gravity
- Infinite fuel: Engines don't drain liquid fuel, oxidizer or solid fuel
- Infinite RCS Propellent
- Infinite EVA Pack fuel
- Whack a Kerbal: throw objects to destroy stuff
- Allow part clipping in editors
