''Locate when Clicked in Empty Space'' in Key Editor

Is there any reason why when using Range Selection or Draw tool in Project window, Transport setting ‘‘Locate when Clicked in Empty Space’’ does not work? And why it is not implemented in Key Editor?
Thanks!

I don’t know about the first question.

In the Key Editor use Alt+sft while clicking.

Turns out in Project window too. Thanks!

Yes, Alt+Sft works in both.

It’s just that in preferences, they added that for the Project Page only.
