It uses the slow method where you push the same key until you get the letter you want to show up? Does anybody remember T9? You push the keys for the letters you want and it figures out what you're typing from a dictionary.

I'm lowkey shocked it's not a esp32 or something. I haven't seen a ATTINY used for a long time.
