Yes, I can see the learning curve is steep, I must be missing something, though, because lowercase letters (26), uppercase letters (26), digits (10), punctuation (26), and "meta" keys like Escape, Tab, Backspace, Delete, and enter (to name a few) exceeds the 32 chorded characters mentioned in TFA.
I've often wondered if Morse Code could be a viable option for data entry on a small screen. Admittedly, there are some punctuation and capitalization issues with this, as well. Yet, it WOULD permit one to text while not requiring one to keep their gaze on the screen.
I suppose one could split the screen in half (e.g. left/right) to distinguish lowercase from uppercase and to allow additional symbols to be defined. I doubt I'm the first to think of this, but I've not seen anything like this being available, I thought I'd toss it out for consideration and discussion.
