In Kerbal Space Program, take charge of the space program for the alien race known as the Kerbals. You have access to an array of parts to assemble fully-functional spacecraft that flies (or doesn’t) based on realistic aerodynamic and orbital physics.

Contents.Modifier keyBecause KSP can run on different operating systems the modifier key ( Mod) differs between them. In the table below, the default Mod key is mapped to the following keys (to use a different key, edit the entry in the'MODIFIERKEY' section of the settings.cfg file):. Windows: ⎇ Alt (e. ⎇ Alt+ L). Mac OS: ⌥ Option (e. ⌥ Opt+ L).
Linux: KSP 1.1+: Right-Shift (e. Right-Shift+ L) Don't confuse this with Left-Shift, which will fire your engines! KSP 1.0.5 and earlier uses a different key, which can cause issues in some window managers when playing in windowed mode.As an example, Mod+ L locks the current stage.
The key combinations in brackets show an example of the respective operating system's key combination: just swap Mod with the operating system's designated modifier.Some keyboards also require to press a to access some special keys like F5. For example, Macs and some Linux devices such as ThinkPad, require Fn+ F5.It is advisable to shutdown your engines if you don't plan on activating them, such as before resource transfers, or if maneuvers have been completed. This will prevent accidental engine activation from a mistyped key. You can disable engines via control groups, or by right clicking on the engine to manually shut it down or activate it.
This can be handy for contracts that require an engine to be tested through staging, but you don't want to discard the usable stage before it: Kill thrust with X, move the engine to be tested to the next stage, then activate the engine through staging. After activation, manually shut down the it tested engine (you'll need to manually re-enable/activate it later). Now you've completed your contract, and haven't wasted any useful stages.
