Configuring an abort sequence using action groups

An action group is a group of part actions that can be triggered using certain buttons or keys. They can be configured under the Action Groups tab in the VAB or SPH.

Available action groups

The tower lifts up the command pod with the Abort action group

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:

To create a sequence for an action group, the action group has to be selected. It then shows all actions which are executed in this action group and it is possible to remove any action from the sequence. When a part is selected it also shows all actions possible which can be triggered and will highlight all parts which are affected. The action apply to all parts which are placed together with symmetry. From there it is possible to add remaining actions to the sequence.
