Shift+1–9 goes straight to that floor

[vyas-meet]

Hop between floors from the keyboard: Shift + 1 to Shift + 9 take you straight to that floor, numbered from the bottom up as the elevator's panel numbers them. It does exactly what picking the floor from the list in the top-left does (switchFloor): a blink and you're on the same spot there, or from outside (balcony, street, garage, roof) the elevator takes you in.

Why Shift

• The bare digits 1–6 are the emotes.
• Ctrl + digit switches browser tabs on Windows and Linux (⌘ on a Mac), and Alt + digit does too in Chrome and Firefox on Linux.
• Shift + digit is bound by no browser on any OS. It's matched by KeyboardEvent.code, so it's the same physical keys on any layout (AZERTY included).

Trade-off: emoting with 1–6 while holding Shift to run now changes floor instead; let go of Shift to emote.

Why floors win the overlap with emotes

The only overlap is Shift + 1–6, which used to play an emote too (the emote keys ignored modifiers). That combination now goes to floors, because getting between projects matters much more:

• Every floor is a project. Hopping between them is the main loop of working in the office: a worker on another floor needs input, N says which floor has someone waiting, a PR merges in another repo, a task spans several projects. That happens many times a session.
• Today it's slow. You either walk to the elevator and press E, or click the project name in the top-left, which takes you out of mouse-look. A keypress keeps you looking around and in a blink you're on the same spot on the other floor.
• Emotes lose almost nothing. They're a social flourish, not part of the work. Bare 1–6 and the G wheel still play them exactly as before. Only emoting while holding Shift to run changes, and letting go of Shift fixes that.

Changes

• src/client/features/floorkeys/: new feature, a ctx.keys.bind on Digit1–Digit9 that acts only with Shift. A floor that doesn't exist, or one still cloning, gets a toast.
• features/emotes: the digit emotes leave Shift+digit alone, so the binding gets it.
• main.ts: one install line, after the other key features.
• Help row (HELP_ROWS), docs/controls.md, docs/features.md and the README controls table.
• tests/floorkeys.test.ts: Shift+2/3 go to floors 2/3; a plain digit and Shift+0 don't.

Verification

• npm run typecheck ✅
• npm test: 607 pass, including size, client-structure and client-help ✅
• npm run build ✅
• No headless screenshot: the only visible change is one new row in the controls help.
