This is how I do it. I'll see something and think 'hmm, interesting' and completely forget any of the details but I'll remember vaguely that something exists then I can search for it.

Language models are pretty good at solving the 'I think I remember something that does this specific thing but don't know where to look' kinds of problems (don't just blindly run LLM generated commands kids). Then once you have a lead, traditional searching is much easier.
