    The thing with a lot of these tricks is that you have to get into the habit of using them. I knew `Ctrl+r` for history since I learned about the command line. I even have a nice shell integration with fzf. But I still used the up/down arrow keys for years or scrolled up when I was looking for a previous command, because I never remembered the shortcut and just took the path of least resistance to find something.

    Usually what I do is writing these tricks down to a document that is easily accessible at a place where I know that I will look for when failing to remember them. I have a directory of docs where I write stuff like this down by language/tool/etc., so I can quickly look it up without having to search the internet. But I also have to actively remind myself that these things exist whenever I have a problem, stop me from just doing the inefficient thing.

      atuin kind of fixes this habit, when you click up you get a list of the latest commands, and you can just start typing to search. It's extremely natural.

        Or you can start typing and press up arrow to search with that. Atuin (or some Zsh extensions, etc.) fix the bad UI of having to remember a different key for "search history by order and text" and "search history by order".
