Is there anything equivalent for Vim or other text editors like TextMate, Sublime, TextWrangler or so? Asking because I don't use Emacs but do use Viim and other apps.
Nothing as complete that I know of. It isn’t crazy to use Emacs just for Org Mode. At least check under the hood and see what you think some time. I know some vim users that use Emacs solely for Org :)
