I have two suggestions for typing derby for accesability that could help people get a better wpm the first suggestion is a keyboard display that can be chosen from a menu of different types like azerty and qwerty during the the derby. That is my first suggestion the second on could be a text to speach for the word that you are currently on that could help people but have this also be toggleble just like the first sugesstion.
I never learn how to type since my high school days… T_T
