A hint about that…
If you open that Note from the dummy person, then you have to leave the Edit Person window open too. Closing the Edit Person also closes the spawned Edit Note window.
To get around that limitation, drag the Note to the Clipboard and open it from there instead.
This is how I always process Obituary transcriptions… Once the transcribed note is attached to the Newspaper, close the Note Editor & copy the Note record to the clipboard. Then close the Citation Editor & copy the Citations record to the Clipboard. Then close Person. Finally, re-open the Note by double-clicking its row on the Clipboard.
Now you can start searching the People view to link the attendees or add the clipboarded citation to the Sources in those Persons.
There are some ugly idiosyncracies when adding links to Notes. One has to do with the crippling of the Clipboard features during the linking process.
When you highlight a name in the Note & click the link button, whatever was in your clipboard is wiped & replaced with the highlighted name. (Wha? Huh? Why would the Link button change the Clipboard buffer?) Worse, you cannot use the Note to temporarily store the clipped data while using the Link feature. That’s because you cannot pick up fresh text from the Note while the Edit link window is active. It is a modal dialog and has to be closed before the underlying Gramps windows can be accessed. You’d have to use an external notepad application to convey the clipboard data. (I usually get bitten by this clipboard discontinuity when copying URLs to make linked text in the note… like a wikipedia definition.)
HOWEVER, when adding a person link, if the Relationship view is active, the Active Person will be the default link target. So you can use the Relationships selection to very quickly link all the sibs, spouses, parents, in-laws listed in an obit. (Sorry… you’ll still have to find those pallbearers, officiants & coworkers manually!)
The Families, People, Sources, & Media category views are similarly able to link without relying on the Select Object Windows. (But it won’t work for Events, Places, Citations, Repositories, or Notes. The People & Combined Relationship have some wonky exceptions too.)
The upside of the links is during the generation of more navigable websites. The downside is that they skew relationship analysis. – The Deep Connections Gramplet gives a Note Link almost as much weight as an immediate family relationship.
