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.

It's not even that bad of a habit with zsh either where it will only scroll through history matching a substring in your history, for instance if I type "rg -i" and then start pressing up arrow, it will only cycle through history entries starting with "rg -i".
if you enable history substring search in zsh you can get that feature anywhere in the command and not just the start. it's very useful if you remember some snippet of the command like it had the word debug in it etc. in fish that is built in and on by default.
though one function that i recently added will narrow your history down based on a space separated set of filters which i found useful
function hgrep
set -l cmd history
for pattern in $argv
set cmd "$cmd | grep -- "(string escape "$pattern")
end
eval $cmd | cat
end
use `hgrep ruby debug foo` would filter for a line that contained all the words ruby, debug and foo.
