I've used a lot of editors, and finally settled on Sublime Text for a bunch of reasons. One was that if I wanted to keep using emacs-derived operation, I could do that, but didn't have to.
I've spent a little time getting ST2 to work with more-or-less standard emacs bindings for character, line, and screen navigation, setting/clearing the mark, and killing/yanking lines/regions. My emacs ability/dependence is not super developed yet, however. I can get around, but it's not like breathing or some other sort of semi-voluntary action.
So I'm thinking about whether to turn on Vintage Mode, and learn those commands -- and what the best place to learn them is. And, if I do, whether I should bite the bullet, dump all my emacs-type custom keybindings and just use vanilla ST2 key bindings for text entry mode, or whether my brain will likely be OK using the (kind of) familiar emacs navigation key combos in entry mode, then switching to vi for complicated editing.
