building graph…
You are told what a shortcut does. Press it.
Spaced repetition: one you miss comes back a few shortcuts later, one you get right comes back much later, and three right in a row retires it for the session.
Pick the contexts to practise — with none picked, all of them are. A shortcut that works in several is still asked once, under the tag it already wears.
No context by that name.
Hold a shortcut: every key your keyboard actually delivers shows up here. A missing one is ghosting, not you.
