Hi Folks,
I expect there's a few people who (like me) are still learning some of LabVIEW's handy shortcuts - and no doubt there's a previous-post about this one (in spite of my searching but not finding it. -

If you work with reentrant VIs and occasionally pop-open a "clone" that you want to edit, try <Ctrl> M.
Cheers!
