Sure that helps. But on Emacs everything is a chord, some quite awkward, and sometimes you have two or three chords in sequence. I don't like bending my fingers, so I use Doom Emacs for Evil.
Exactly, those defaults are a disgrace and also are surprisingly difficult to change, particularly when the action includes a mini-mode with its own key bindings so you remap a key, but then it still does not work after the first key press. Yes, you can find all the variables you need to change to remap a specific key but it wastes way more time than it should.
As Emacs was ported, they replaced dedicated keys with chords and sequences and we ended up in this mess, instead of at some point doing a full review of the default keybindings to match the input devices we actually have, merging in the conventions that had developed in the meantime.
After three decades of use, I have internalized those defaults because I keep having to use Emacs in its default configuration from time to time, have remapped many keys in my workstation, bound custom functions and all that. It’s still a paper cut, and also prevents me from recommending Emacs to more casual users.
