Uses
An action group can cause any action that can also be triggered by right-clicking a part and making a selection from its popup menu. This makes action groups useful for coordinating the functions of multiple parts all over a spacecraft, or for making the same change to several identical parts. Action groups trigger all their parts simultaneously, allowing quick changes in situations where using the popup menus would be impractical or dangerous, such as surface landings or while the engines are throttled up during a maneuver.
Common uses of custom action groups include:
- An abort or command module ejection sequence.
- Extending ladders along with landing gear.
- Switching active engine groups on complicated crafts such as VTOL planes.
- Toggling the gimbal lock of all engines.
- Deploying solar panels.
- Activating multiple environmental sensors.
