Hi! Thanks for the PR request. We were actually in the middle of creating the CharaChorder Lite page when you submitted this and I meant to get back to you. We just made that live, which has images of the default layouts.

I think that this would be valuable to add if these are in fact default mappings, I need to confirm that

The screenshot of the A2 layer has the functions represented as icons.

A table would be good to add because it makes it easy to Ctrl + F to find the shortcut in the docs.
