I have an old Fire tablet that I’ve put LineageOS on. It’s long in the tooth, but even with its crappy Amazon kernel it runs fairly nicely if I don’t stress it. I’d like to have it as a no-distractions writing device with one of my mech keyboards paired to it.

I’m looking for a lightweight markdown note taking app or word processor that does not need a ton of features, but I would like support for simple keyboard shortcuts like ctrl-I, B, U, X, V and I’d prefer WYSIWIG display for any light formatting that markdown would support.

Any ideas?

EDIT: Seems like Markor is the first recommendation to check out. Thanks!
