With version 10.3.1720 (b574c3b), I was able to define shortcut keys for tags:
This was so useful as I come from Postbox where I had this defined.
But when I start writing a new email, number keys 1, 2, 3 don’t work in the body of the email
They work in the To, Cc, Bcc fields and Subject field.
Bug? Feature?
