Drill all 44 until you don't have to think about them.
triage the stock inbox — macOS
Stock Mail on macOS — chords verified against Apple’s own shortcut list. New Message (⌘N) is browser-reserved and sits out, like every deck’s reserved chords. Flag has no reliable default shortcut, so it isn’t drilled — neither do VIPs or expand/collapse-all conversations; thread stepping (⌥↑/⌥↓) is.

How graduation works. Drill until every move in the deck holds at ≥95% first-try, under 800ms median, across two separate days. Then the deck is done — and you get a certificate stating exactly that, plus a LinkedIn credential in one click.
