Just to point out, on android, you can use the personal dictionary..

I have, for example, ♭ with a shortcut of "-flat"

Then if I type -flat the ♭ comes up as a suggested correction.

Thanks, I need to spend a bit of time working on this.

Well, I think I was able to do this.  Not sure if this is the best or most elegant way of doing this, but....

Basically I copied the flat and natural symbols online (or maybe from Word?).  I was able to paste them into "suggested punctuation" in Hackers Keyboard.

Now, if I want to use them while I am in a  Mobilsheets song, I click on the "Settings" icon in Hacker's Keyboard.  I scroll down to "Suggested Punctuation" and I am able to copy and paste them in the song I am working on.

It's a bit unwieldy, but not too bad.  Basically I would copy and paste the flat and natural symbol once into the song.  Then I would copy and paste them whenever I need them. The spacing seems fine (I have only tried it once).  But I think I will use that flat symbol a lot so I can now use lower case letters for notes (and have the option of a flat and natural symbol) while using upper case for chords.  All seems good.
