Dark theme (on Mobian)?

[TRS-80]

OK, I found it.  There is not a setting in the menu, it's in a config file as described here.

I knew I had found that before, just forgot where.  Got wiped when I had to reinstall.

I actually like that things are in text config files.  Opens the door to keeping dotfiles in a git repo, just like I do on standard GNU/Linux on desktop and laptops!

Also, I forgot just how much good info was over there at Mobian Wiki.  Another reason I like (and chose) that project / distro.
