Don't waste your time with these cryptic editors. Get a more reasonable editor such as Sublime Text or VSCode that allow you to install plugins for emacs/vim bindings etc.
IMHO the best bang for buck that you get with these editors comes from learning just a handful of commands for the most common stuff, i.e. open/close/save, move caret, cut/copy/paste/, switch between buffers. So with a more modern editor with emacs/vim like plugin you can have the best of both worlds, i.e. enable fast operations for the common stuff while also having sensible menus etc. for the non-common stuff. If you go "raw" emacs/vim, then everything is cryptic.
