i feel like a handful people have recommended that you use vim as a text editor during your keyboard shortcut blitz (it's philosophy kind of ties into that). have you tried using it? and if you have, what do you like/dislike about it?
i've been using textedit for like 100 years, so it might be difficult to get me to switch ...... the only thing i've ever wished for that textedit doesn't have, is the ability to skip to exactly the end or beginning of a sentence, and the only reason i ever wanted that was for the purpose of of more quickly reaching the insert point for a subanswer in these questions. but as of today i found a way to do it via regex and keyboard maestro. thought it would be clunky and slow because regex can't actually move the cursor, i have to highlight, copy, regex search, count characters, and use the arrow key. but then after re-writing it so it counts words instead of characters, and then using opt-arrow instead, it's down to about .2 seconds
