I’m using a bluetooth keyboard with Android 11. In Jerboa’s text fields, the left/right cursor keys work alright but up/down seem to work outside of the context of the text box. Meaning, those keys will switch the focus between form elements rather than moving the cursor inside the text box. With muscle memory already in place, this is of course a major inconvenience.
I’m aware that the dev has a lot of work to do right now, so i didn’t tag this as a higher-priority bug.

edit: switching between UI elements on Android applicatons is usually done with the Tab key. Jerboa uses the Tab key in text fields more in the original way, inserting a Tab space. Those are used in markdown as a monospace text indicator, so that is useful. In other text fields, Tabs might get converted to spaces, anyway.
