I try to always create a tag from people’s names in my notes - for ease of searching, to see unexpected connections via ‘related notes’, and in the hope of exciting funcationality when people tags integrate with Apple Contacts.
Howver, types @ and ( ) around the name all the time is pretty tedious. (The name is often already in my note as it’s created from a calendar event).
It would be really helpful to be able to highlight a name, and them hit a key combination to turn the name into a person tag - on MacOS. I assume on iOS it would need to be highlight text and then a menu command.
