I’m currently on a TLK, and mostly because I want to learn to stop moving my hands away from the home row. It’s not even only about arrows, but also home/end page up/down etc. and combinations with them which I use a lot and it just get slow and weird since I have to reposition my hands every time… mine is currently quite limited in what I can program it to do unfortunately.

Peoples are mostly angry at the fact that they just silently slipped this system in without asking for consent.
