How to select object when Eyedropper Tool activated?

[#1]

Is there a keyboard shortcut that allows you to select an object when eyedropper activated, without having to click on selection tool and the eydropper tool again? 

LIKE: Eyedropper is turn on, click on (example) shift, select object, release shift and eyedropper is back... 

I know the following approach which is a click longer.
from eyedropper, click V, select object, and click I for eyedropper.

Holding command (Mac) or control (Win) will activate the last-used selection tool while the key is held.

Thank you. I try Shift, Ctrl, Alt, other keys combinations.... but maybe I missed seeing it.
