My favorite (evidence backed) theory on how humans learn is Retrieval Practice.

Humans don’t really learn when we download info into our brain, we learn when we expend effort to pull that info out. This has some big implications for designing collaborative tooling!

The “thing” that we learn most effectively is not knowledge as we typically think of it, it’s process. This should be intuitive, if we put into a bit of a more natural context. Imaging learning baking for a moment: Do you teach someone to bake a cake by spitting out a fact sheet of ingredients and having them memorize it? Or do you teach them the process?

If you feel, not unreasonably, that both Vim and Emacs’ keyboard command systems are bizarre and arcane, you can customize Readline’s key bindings and make them whatever you like. This is not hard to do. Readline reads a ~/.inputrc file on startup that can be used to configure various options and key bindings. One thing I’ve done is reconfigured Ctrl-K. Normally it deletes from the cursor to the end of the line, but I rarely do that. So I’ve instead bound it so that pressing Ctrl-K deletes the whole line, regardless of where the cursor is. I’ve done that by adding the following to ~/.inputrc:
