Good concept!

The important thing to know when learning hotkeys is how to perform the same action using application UI.

Otherwise the keyboard becomes an obscure medium for discovering application functionality

I've been using Blender for over 5 years. I'm also active on Blender.stackexchange.com and when I help someone there and write instructions, I'm always confused how to navigate to a particular thing using a menu (mostly because some operators' place is ambiguous e.g. "select" vs "mesh" vs "vertex". I think there's a lot of users like me, for efficiency you're just supposed to use shortcuts.

You wouldn't use a menu in notepad to cut/copy/paste, select all etc. right?

It's funny how, when I actually look in the menu, I discover some new things added in recent versions of Blender.
