TIL!
Can exit nano on my own, have the common sense to not call in a panic about it before at least looking it up. (Which is how I learned how to exit it: looking it up.) But was never taught about ^ meaning "Control+" until your comment, especially since nowadays people write it out as "Control+" or "CTRL+".
I might have put two and two together when dealing with everything else in nano after I learned to exit, but never really internalized the rule "^ means Control+". So thank you for your comment!
Disclaimer: I feel like I am too stupid for most of programming.dev but participate here anyways because I learn stuff from the comments.
Can't think of anything that could serve a major need right now, but I absolutely identified things in my life where I could use a preexisting tool to accomplish my goal, but it's much less hassle for me to use the one I made for myself. You don't have to transform the world, sometimes you can help yourself with a minor inconvenience and then put it out there for anyone who might find themselves with the same inconvenience.
