Not sure what you mean by modal keyboard, but there is fully customizable row of keys in termux.

I disabled it, because I use special android keyboard app[0] with a custom layout made from scratch[1]: all common symbols, arrows, esc, ctrl, alt, forward delete, paste and enter gestures etc. etc.

Well, the modal command system is sort of hacked onto the qwerty keyboard. Surely it'd be more natural to just "insert" directly rather than hitting "i".
