Add multiple keywords to single photo without having to re-focus the cursor
I use keywords a lot, but since updating to Catalina, I seem to be having an issue adding multiple keywords to a single photo that I don't think was there before the update. Whenever I enter a keyword, the curser disappears from the Add Keyword field, and I then need to use the trackpad to refocus it back to that field. This gets very annoying if I'm trying to add 5 or so keywords to potentially hundreds of photos. Is this a new bug, or have I just not noticed it before. Is there a keyboard short cut that will take me straight to the Add Keyword field so I don't have to bother with the trackpad?
