If you're working with reentrant VIs, particularly preallocated reentrant VIs, you will often need to access the "original" VI to edit it. But sometimes, you'll only have clone instances of the VI open. One way to get to the original VI from a reentrant instance is View > Browse Relationships > Reentrant Original. But an even easier way is to simply press Ctrl-M on the clone instance...this will immediately bring up the panel of the original VI.
