When I forget where I've stashed a specific symbol or similar I just check the Via QMK configuration tool, similar to when you're trying to learn the shortcut keys for a piece of software. Eventually it's muscle-memory, but it's nice to have a reference guide whilst you're building it.

When I learned Dvorak I found a tiny picture of the layout and stuffed it into a corner of my desktop. I didn’t usually have to look but sometimes.

I still forget where the symbols are regularly, which ends up evening out my typing speed versus sticking with qwerty.
