How to get the feature which is under edting ?

AS the topic mentioned, how to get this feature ?

look, the sketch was under edting, that means the object was specific, I think there is no need to click a select to get a selected object, then get the feature, and then call its method/memeber .

Is there any better way to make it ? 

thank you
