Actions: Control Double Click Plays Selected State

[animationlife]

Hello Everyone.

I noticed, If you have an Action with many States, and If you Control+Double Click on that State, It plays that State only. This Is good If you only want to play the action State, rather than playing the entire action

So ctrl-double-click the Action itself.

Exactly it is useful. 
Double click on any action steps apply this step only.
