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.

Yeah I thought he was going to say it uses T9 too, but it uses an inexplicably archaic chip so there's no way you could fit a dictionary on it.

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

ATTINY works as well as the day it was born :)
