Simultaneous Actions (Animation)
Make synchronous actions execute at the same time
By default, all actions are executed successively one by one.
If you want to make two (or more) actions animate at the same time, you can easily do this in the animation timeline in the animation tab.
Just toggle the "rewind the clock" icon to make an action execute at the same time as the preceding action.
If you want to make 3 or more actions execute at the same time, toggle the "rewind the clock" for every action but the first one.
