I'm sure that almost everybody configured emacs in some way or another, but how many people shared their configurations, and where can I get them? I'm interested in something like starter packs, in things that make keyboard hotkeys less painful for newcomers.
I know of a handful of modes and distributions that are along these lines, though ultimately I tuned my own bindings based on my usage.
Emacs itself has CUA mode, which makes many keybindings more like newer editors. There's also Spacemacs, which, among other things, includes keybindings that are more like Vim. better-defaults alters the behavior of certain keybindings, rather than the bindings themselves. If you're focused on RSI issues, ergomacs-mode might be worth a look.
If you want to tune any of these further for your specific use case, I highly recommend checking out hydra.
