Outside of the text editor, I think native emacs keybindings like (C-n, C-p, C-a, C-e, C-k) on OSX are great and I hope they never get rid of them.
As a user of these key binding in both Emacs and macOS, it’d be worse than cutting off an arm if this went away
Or all movement combined with prefixes. I regularly do
C-u C-u C-p
Separately, macros, yea! Macros with regexes FTW! The counter you can use in macros - occasionally very useful! M-x occur! Dired which can search a whole directory tree of file contents for a regexp! So much more.
Only thing worse than emacs interface is not having emacs at all.
Accessibility feature in macos where modal / control keys will "stick" for the next keypress (non-modal / control) and then release.
Double tap will stick it for the duration until the next tap on the same key.
Essentialy, double tap control key and move around with n and p keys, kill with k, move more, yank somewhere else with y. All without touching control! But there's more, you can save the buffer with x followed by s press. It takes a while to get used to but saves you awkward wrist moves. I guess it's closer to modal editing in vi, just not as advanced.
Every time I work with Linux or Windows, when I open a Chrome tab and I want to go down to a history completion, I hit C-n multiple times and it ends up with many new windows...
