When I need to remember how time formatting works, I go to the incredibly concise and helpful Python strftime reference (Private).
I wish there were something similar for Mac commands, shortcuts, etc. I just had to look up how to choose the startup disk on startup (hold down the option key). To remind myself of the correct answer, I wound up scrolling down an incredibly bloated, ad-filled “article” on some website.

If not, maybe it’s time to start one. It might include the keys to hold down for whatever zapping the P-RAM is called these days.
