helpful snippets that I keep forgetting

these are things that I use often enough that I want quick access to them, but not often enough (at least at time of recording) that I remember them on my own.

The idea is that if I need somethign I know I already looked up, I'll add it here. Hopefully that'll mean that I can get it more quickly in the future, and that will lead to me using the useful thing more often, and that'll lead to me actually remembering it, and I'll only ever be referring regularly to things at the bottom of the list (which'll make it even easier to find).

That's the goal.

Feel free to suggest other helpful snippets, but this is by design and intent really opinionated. If I get a suggestion for something I actually decide I should use, I try it, and it's great, I'll add it iff I need to use it again and can't remember it.

The actual snippets
