You can gang clips and sequences together on the Desktop so that when you jog one, they are all jogged. This is useful for multicam setups. When you play a clip that is part of a gang, the current frame of all other ganged clips is updated once playback has stopped.
To gang two clips on the Desktop:
The selected clips are ganged and the clip information turns green.
To select all clips in a gang:
All ganged clips/sequences are selected.
To remove a clip from a gang:
All selected clips and/or sequences are unganged.
