Shortcut Trainer shows you an action — Delete line, Go to definition, yank line — and waits for you to press the actual key combination. Get it right and your streak climbs; get it wrong and the answer flashes so the correct motion sticks next time.
Three decks ship in the box: VS Code, Vim (including multi-key sequences like dd and :w), and the terminal. Best streak and accuracy persist per app, so you can watch yourself improve.
