The subject says it succinctly: How can I copy the (non-group) tags from one record to another (in the same database)?
Is there a built-in way to do this? Or is there a script for this? - Thanks for your help in advanced! 
Why don’t you just copy and paste them between files?
Also, a script wouldn’t necessarily be a good approach unless you were just copying the Tags to the clipboard for a manual paste on the other file.
Yep, that works. Thanks.
Is there a keyboard shortcut to get into the tag area at the bottom of the document? Without this, you need to be quite a mouse-virtuoso to copy the tags…
Control-Return (as noted in the menu item Edit > Tags…).
Alright, that’s one direction: Ctrl-Return gets me from the selected note/note text into the tag bar. - But how do I get via keyboard back to the note?
I prefer Control-Tab myself. It actually cycles from the document list, to the document, to the tag bar, etc. Shift-Control-Tab cycles back, so you can use that combo as a toggle.
Thanks. To move around by keyboard this is good suggestion.
