+### 2.1 Three kinds of action
+
+Most things need no vote at all. A vote is for power over other people, and for decisions that bind a whole body.
+
+| Kind | What | How |
+| --- | --- | --- |
+| **Free** | Everyday actions inside your own role (the list below, and anything of the same weight) | Just do it. Kira logs the ones she sees in #staff-log. The tier above can reverse it; if people disagree, the tier above votes. A pattern of abuse is a recall |
+| **Body vote** | Giving or taking a role that carries power (an election), or a decision that belongs to one body: the mods, the Team, a group | `/elect` or `/vote body:` in Kira (section 5.3). Any council member can call a veto within 24 hours |
+| **Council poll** | Rules, money, accounts and ownership, the council's own members, vetoes, anything that spans several bodies | `/poll` (section 4) |
+
+Free actions, for example:
+
+- a lead gives or removes their group's helper role (🧩 Horizon Modding Team), through Kira;
+- a moderator gives or removes 🤝 Support, through Kira;
+- a moderator times out, deletes, quarantines, or changes a channel's slowmode or topic; the Chief of Mods bans and
+  unbans;
+- the Team merges and labels;
+- a server operator restarts the official server, or prunes backups and chunks by the written rule;
+- a lead pins, renames or creates threads in their group's channels;
+- Kira's automatic actions.
+
+**The 24-hour rule.** Every vote lasts 24 hours at most, and closes earlier once its result can't change. Only council
+polls on this document, the licence, money and the GitHub organisation's ownership last 48 hours. A veto is called
+within 24 hours of a result.
+
+### 2.2 Who may do what

-   - A **council member** can only be nominated by a council member.

-2. **The filter.** Kira checks the floor and the 18+ declaration. Below the floor, Kira refuses and says which line
-   is short.
-3. **Public discussion, 24 hours.** Kira posts the nomination and the evidence card in a thread of
-   #polls-and-decisions. Contributors and the council can comment. For a lead, Kira also runs an **advisory poll** in
-   the group's channel for the same 24 hours. Only active group members vote in it, and the council sees the result.
-4. **Council poll, 24 hours.** Simple majority for a lead, 2/3 for the Team and the council. For moderators, the mods'

-5. **Probation, 30 days.** The role is held in full, except for the Team limits in section 3. At day 25, Kira asks the

+and has at least one merged pull request or review with the group's label in the last 60 days.
+
+1. **Start.** Kira checks the floor (5.2) and the 18+ declaration. If the candidate falls short, the person starting
+   gets a private "not now", and the candidate a private message saying what is missing. Nothing is posted and no
+   reason is ever shown to anyone else. Kira checks what she can measure (verified GitHub, merged pull requests and
+   reviews, overall and by the group's label, rank, days in the server, Kira level, clean record, the declaration);
+   the voters judge the rest.
+2. **Vote, 24 hours,** in the body's channel, discussed in the vote's thread. Yes, No or Abstain, changeable while it
+   runs. Kira shows how many voted, never who. It closes early once the result can't change.
+3. **Result,** applied at once. Kira gives or takes the Discord role and, with a token, the GitHub team; she lists the
+   rest as clicks for a named person. Only the result is published, never the ballots.
+4. **Veto, 24 hours.** Any council member can call it with the button under the result. A council poll (simple
+   majority, without the people involved) decides; if it passes, Kira undoes the result.
+5. **Probation, 30 days,** for leads and Team members. It ends by itself unless someone who can vote starts a recall.

+| The council is already voting on it | No election starts for the same person and post |
+| Cooldown | A failed or vetoed election can't be started again for the same person and post for 30 days. At most 3 elections run at once in a body |
+| Vacancy | When a lead or the Chief of Mods leaves, Kira opens the seat's election herself: 24 hours of nominations, then the vote with everyone nominated. Nobody nominated: the seat stays open, and the tier above acts meanwhile. Kira never picks a candidate |
+| Abuse of a free action | The tier above reverses it; a disagreement goes to its vote. A pattern is a recall |
+| Emergency | Section 4.6. The Chief of Mods can still suspend a mod at once |
+| Kira is down | The body may run the same vote as a Discord poll in its channel for 24 hours; Kira records the result when she is back |
+
+#### Reminders, not nominations
+
+Once a month in a group's channel, Kira says how to propose someone, only when the group has no lead or someone in it
+meets a post's floor. When a seat opens, she posts once in the electorate's channel. Once a month in #council, she
+lists privately the people who meet a floor. These are suggestions: only people start elections.

+## Radial menu
+
+Hold the opener and the right stick points at one of eight slots, clockwise
+from the top; letting the opener go runs the selected action, once. It isn't a
+screen: the world goes on behind it, and neither the selecting stick nor the mouse
+turns the view while it is open (the stick not until it has been let go). With
+the default opener, D-pad Right, the left thumb is on the D-pad, so the player
+stands still while picking; with the opener on a bumper, a trigger or View the
+stick that doesn't select still walks or turns the view.
+Every hold opens on the first page, so a flick aimed blind always lands on the
+same slot.
+
+Two settings in Controller Settings > General, under Radial Menu, change how it
+is held and aimed, saved as `radialMode` and `radialStick` in
+`horizon-controller.txt`:
+
+- Radial Menu: Hold (the default) or Toggle (`radialMode:hold|toggle`). In
+  Toggle a press opens it, shown at once, and it stays open with the opener up:
+  A or a second press of the opener runs what is selected, B cancels, and with
+  nothing selected nothing runs.
+- Radial Menu Selects With: Right Stick (the default), Left Stick or Either
+  (`radialStick:right|left|either`). The selecting stick neither walks nor
+  turns the view while the menu is open; with Either, the last stick to lean
+  past the select tilt selects, and neither moves anything. While the menu is
+  open a stick takes over only once it has been at rest since the open, so a
+  thumb left on the walking stick can't commit for the other. Its tilts follow
+  that stick's own deadzone.
+
+- The overlay shows once the opener has been held 120 ms (`DRAW_DELAY`); the
+  stick counts from the press, so a quick flick-and-release works without it,
+  and a tap that selected nothing shows nothing and does nothing. A flick
+  between two frames still counts: the pad's own events give the furthest the
+  stick leant since the last poll.
+- The slots are eight tiles (vanilla's game mode switcher slots, each with its
+  action's icon from the player's own resources) on a ring at true 45 degree
+  steps, where the stick selects them; the selected sector lights up behind
+  its tile. The hub in the middle names the selection; for Perspective, Hide
+  HUD and Cinematic Camera it gives the state and what a press turns it to,
+  and for a slot that can't run, why (`Needs cosmetics on`). An empty slot is
+  a pip, one that can't run is dimmed and slashed, and a missing action (an id
+  this game doesn't know) says Missing. Along the top, the pages are tabs
+  between the bumpers' glyphs, the current one white; on a narrow view they
+  collapse to the name between arrows, with the bumpers naming the pages they
+  turn to. With a bumper for the opener only the other shows, and with one page
+  only its name. B's Cancel sits at the lower right when the view has room. The
+  header stays below vanilla's boss bars and the ring above the status rows
+  over the hotbar (armour, health with absorption, food, a mount's hearts);
+  while the menu shows, the chat lines, the toasts, the crosshair, the guide
+  and the first-person hand give way (none of them blink on a quick tap,
+  which draws nothing). Sizes follow the
+  view's height (`radial_overlay::Layout`), so 1280x720, 854x480 and a quarter
+  of a large window look the same, and smaller views drop the state chips and
+  the Cancel hint first. Its motion is quiet and never selects: a quick fade in,
+  the lit sector easing to a new slot, the tiles sliding in on a page turn, the
+  chosen tile flashing on a commit (`hud_kit::motion`, settled while the game
+  is paused or recording).
+- Bumpers change the page, around the ends, and clear the selection; with a
+  bumper for the opener, the other one turns the pages on. A stick held through
+  the page turn selects nothing until it moves. One that had leant past rest
+  for 90 ms before the opener went down (`LEAN_BEFORE_OPEN`, a stick turning the
+  camera) selects nothing until it has been at rest, page turns included; one
+  that moved only just before is a flick aimed at the menu, and selects.
+  Meanwhile the sector stays dark and the hub says "Let go of the stick".
+- A selected slot stays selected a little past its wedge and under the tilt, so
+  a light hold or a stick on a boundary doesn't flicker. The tilts are tuned at
+  the default look deadzone and keep their share of the travel past a raised
+  one (`radial::Tilt`): a selection always lets go above the deadzone, so a
+  drifting stick never keeps one, and no slot ever needs more than a 0.93 lean,
+  which a worn stick still reaches.
+- With vibration on: reaching a slot that would run gives a tick (45 ms on the
+  light motor), a page turn a shorter one, twice when the pages go round an
+  end, and a release that runs nothing after something was selected a soft
+  buzz. A commit that runs an action plays the button click.
+- With the narrator on, it says the page's name as the overlay shows and after
+  each page turn, and a slot's caption once the selection has stayed 150 ms
+  (`NARRATE_SETTLE`), so a sweep across slots says only where it stops.
+- A stick let go keeps its selection for 250 ms (`NEUTRAL_RETENTION`), so it can
+  spring back before the opener comes up; then the selection clears. Latched
+  open in Toggle the selection stays with the stick let go, so the thumb can
+  move to A: only another slot, a page turn or a cancel changes it. A slot the
+  thumb crosses on its way to A, selected less than 90 ms before A goes down
+  (`A_SETTLE`), doesn't count: A runs the one it had settled on.
+- A release with nothing selected, or on an empty slot, does nothing. An empty
+  slot is a faint outline with no caption; only the selected action takes the
+  accent.
+- An action that can't run now is drawn dimmed. It can be selected, but its
+  release does nothing: no action, no click. The game decides which: Emote
+  opens the emote wheel only with cosmetics on, Quick Actions only when the
+  server gave a dialog for it, and Social only on a server. Social is the one
+  exception to doing nothing: in single player its release goes through its key,
+  which shows vanilla's "not available" message on the action bar, as
+  `Gui.handleKeybinds` does (pressing its key does the same). A Missing action
+  never runs. The others always run.
+- B, Start, a disconnect, losing the window's focus (with Play in Background on
+  too), the player being replaced (a death with immediate respawn, the End's
+  exit) or anything that opens over gameplay cancels, also during those 250 ms.
+  RT or LT pressed while it is open cancels it and goes on to attack or use in
+  the same poll; so does any key or mouse button, which isn't swallowed. No
+  other press made while it is open reaches a mapping, and a press in the same
+  poll as the opener's release, held back to the next tick or not, comes first,
+  so B still cancels. Buttons held since before it opened keep their action and
+  release it as usual, so a held sneak stays held. Moving the mouse neither
+  cancels it nor takes control back from the pad, nor turns the view.
+- After it closes on a D-pad opener, a press of another D-pad button that starts
+  within 100 ms reaches nothing, and nor does its release (`DPAD_SETTLE`): a
+  thumb rolling off the opener doesn't drop or open the chat. The opener itself
+  opens the menu again at once. A drop held through it starts
+  its wait again as it closes, rather than throwing the rest of the stack. F3's
+  3D crosshair gives way to it, as the 2D one does.
+- Menus, the on-screen keyboard and prompts come first: there the opener's
+  button does what the screen says (or its other action, if it shares one).
+- The opener is never under a thumb that selects, as holding it and steering
+  are two jobs for one thumb, nor on B, which cancels (`gamepad::opener_refused`):
+  selecting with the right stick, not A, X, Y or R3; with the left, not the D-pad
+  or L3 (A, X and Y are free); with either, neither set, leaving the bumpers,
+  the triggers and View. In the binds list a refused button cancels the capture
+  as Start does, and a file with one reads as if it had no opener saved (D-pad
+  Right, unless another action is there or the stick refuses it). Changing the
+  stick so that the opener is under the selecting thumb unbinds it, and the
+  opener's row says no button opens the menu and which ones can; back on the
+  right stick an unbound opener takes D-pad Right again if it is free. A bumper
+  can be the opener; the other bumper then turns the pages on, round the end.
+
+The default pages hold only actions with no button of their own that always
+run, so the menu adds to the pad instead of repeating it, on the straight
+directions: General has Advancements (up), Commands (right) and Social (down);
+Camera has Screenshot (up), Hide HUD (right) and Cinematic Camera (down). The
+rest start empty. Slots hold actions from a fixed list
+(`radial::RadialAction`), those that do everything on their press (Fullscreen,
+Quick Actions and the F3 debug screen besides those of the default pages), each shown
+by a short caption (`horizon.radial.action.*`). Its rules are in
+`horizon-client-input/src/radial.rs`, the overlay in
+`horizon-client-render/src/radial_overlay.rs`.
+
+Pages live in `horizon-controller.txt`, written once they differ from the
+defaults, so each splitscreen profile has its own, after `radialLayout:1` (the
+version of the default page list they were written against). A page the player
+hasn't changed is written as its preset, `radial_<page>_preset:general` or
+`camera`, and reads back as that default page as it is now: changing one slot
+of General leaves Camera following the defaults. Setting a slot or a name to
+what it already is changes nothing, and a page edited back to its default (or
+read from its slots as that) is its preset again; an edited page drops a preset
+id this game doesn't know, which would otherwise replace it. A page of the player's own is
+`radial_<page>_slots` (eight ids, by commas) and its name as
+`radial_<page>_name` (a name Horizon gave it, by language key) or
+`radial_<page>_label` (the player's own text, kept as typed);
+`radial_<page>_kind:hotbar` is read and kept for a hotbar page, which this
+version shows with empty slots. Slot ids are vanilla key mappings by name
+(`key.chat`) and Horizon's own in its namespace (`horizon:emote`,
+`horizon:hotbar_next`, `horizon:hotbar_previous`); the ids they had before
+(`key.emote`, `pad.hotbarNext`, `pad.hotbarPrevious`) read through an alias
+table. An id this game doesn't know (a newer Horizon's, a mod's) stays in its
+slot, drawn as Missing and dimmed, and never runs, so a slot can't run a
+command. Fields and kinds it doesn't read stay too. A file can hold up to 16
+pages (`PARSE_MAX`), and the lines of any past them are kept; the menu and the
+editor show the first six, and a page deleted there brings the next forward.
+Removing an action empties its slot and moves no other.
+
+Controller Settings > Bindings > Radial Menu edits them, on the settings shell
+(`horizon-client-render/src/radial_editor.rs`): the page list is the pages, by
+name, and each page has its eight slots by direction (A or a click opens the list
+of every action and Empty for that slot, which names the slot, marks what it holds
+and opens on it; Right steps a slot to the next action, Empty between the last and
+the first, and Left or Shift-click back, as on every choice of the settings shell),
+then Rename Page, New Page
+and Delete Page, then Reset All Pages and the opener's button, drawn with its
+glyph. A press on the opener's row waits there for a controller button, as a key
+row does: A, B, X, Y and the right stick's click are refused, Start cancels, and
+the row's description says when no button opens the menu or another action
+shares it. Delete and Reset act at once: Undo, there once something changed, puts
+the pages and the opener back as the screen found them. Rename opens a page with
+a name field (A on it opens the on-screen keyboard), Done and Cancel.

-# Operations: running Horizon by hand
-
-How the Horizon Team and the council keep Horizon working when no AI agent is running and the maintainer's machines
-are off. Each section says what normally happens by itself, who can do it by hand, and what to do when it breaks.
-How decisions are made is in [GOVERNANCE.md](../GOVERNANCE.md); how a change reaches players is in
-[release-flow.md](release-flow.md). This page only says how to operate them.
-
-## Who can do what
-
-| Who | Can |
-| --- | --- |
-| **Horizon Team** (GitHub team `horizon-team`, write access) | Review, label and merge pull requests; approve a fork's workflow runs; re-run failed jobs; start workflows by hand (`gh workflow run`); add `release-blocker` to an issue; merge in horizon-mods (form pull requests too) and upload its `staging` files |
-| **Trusted reviewers** (`.github/trusted-reviewers.txt`) | `/nightly`, `/close`, `/reopen`, `/label`, `/unlabel`, `/unclaim` by comment ([release-flow.md](release-flow.md#trusted-reviewers)) |
-| **Council** (🏛️ Council on Discord) | Decide by poll (`/vote`, `/poll start`); emergency actions (GOVERNANCE.md 4.6) |
-| **Organisation owners** (today: Ludovic only) | Repository variables and secrets (`SELF_HOSTED_CI`, `RELEASES_PAUSED`), branch protection, adding people to GitHub teams, merging past a missing review, the security advisories |
-| **Code owners** (`.github/CODEOWNERS`, today: Ludovic only) | Approve pull requests that touch `.github/`, `tools/ci/`, the release, signing and update code |
-
-The council's first poll gives the organisation a second owner (GOVERNANCE.md section 11). Until then, anything in
-the last two rows waits for Ludovic.
-
-## Merging a pull request
-
-Nobody merges automatically. A Team member:
-
-1. Reads the whole diff. For a fork, do it before approving its workflow runs (they wait under **Actions**:
-   "Approve and run") and before adding `run-parity`.
-2. Waits for `verify`, the one required check. A pull request that changes no Rust finishes it in about a minute.
-3. Merges with a merge commit once `verify` passed, no change request is open and every comment has been read. A
-   "don't merge" from anyone holds it. Never merge your own pull request, never use `gh pr merge --auto`, never
-   force-push a contributor's branch (merge main into it instead).
-
-Risky pull requests (saves, the network or server thread, world generation, the launcher's installs and updates,
-the harnesses, anything over ~500 lines) get `needs-proof` and wait until someone has played the change: both
-single-player paths, a LAN guest, a screenshot for anything visible. The list is in
-[release-flow.md](release-flow.md#merging).
-
-A pull request that touches a CODEOWNERS path needs a code owner's approving review: GitHub keeps its merge button
-locked until then. Leave it open and say in the thread that it waits for a code owner.
-
-Pull requests opened by the maintainer's agents (author `ludovic111`, body starting "Opened by Ludovic's AI agent")
-are ordinary pull requests: review and merge them like any other, or close them if they went stale. Closing keeps
-the branch.
-
-## Releases
-
-Everything below runs by itself on GitHub; you only step in when something is wrong.
-
-- **The Nightly** is the only build players get. The train (`release.yml`, every 10 minutes) starts one after 5
-  player-facing merges, or when the oldest has waited 6 hours, or at once for a pull request labelled
-  `release-now`. Only a commit where both `checks` and `parity-main` passed ships. Who may add `release-now` is the
-  council's choice; until it decides, leave the label to the maintainer.
-- **Stopping Nightlies:** open an issue about the problem and label it `release-blocker`. Nothing is published
-  while it is open, forced builds included. Close it when the fix is on main.
-- **Rolling back:** revert the pull request and merge the revert. Players can pick an earlier build on the
-  launcher's Versions page meanwhile.
-- **The reviewers' picks:** `/nightly status` shows the set, `/nightly clear` builds main alone.
-- **Launcher releases** follow the same train (`launcher.yml`).
-
-The Nightly's macOS builds, its smoke test and parity-main run on the maintainer's Mac mini. While it is off,
-**no Nightly and no launcher release can be published**: players keep the last ones, which keep working. See below.
-
-## Self-hosted runners are offline
-
-Some jobs run only on the maintainer's machines, because they need his own copy of Minecraft or a Mac
-([ci-runners.md](ci-runners.md)). When those machines are off, those jobs wait up to a day and then fail. The
-**runner watch** opens one issue, "CI: self-hosted runners are not taking jobs", within about 2 hours, listing what
-is waiting, and closes it once the runners are back.
-
-| Runner label | What waits | What to do |
-| --- | --- | --- |
-| `horizon-light` (bots) | Triage and claim commands, labels, overlap notes, the Mojang check | An organisation owner sets `SELF_HOSTED_CI` to `off` (Settings → Secrets and variables → Actions → Variables). Then everything runs on GitHub |
-| `horizon-checks` | `verify` of this repository's own pull requests ending in 0 or 1 | Same switch (`off` or `light`), then re-run the waiting checks. Forks' pull requests never use these runners |
-| `horizon-game` | A pull request's own parity job | It isn't required: merge on `verify`, and label pull requests that touch gameplay `needs-proof` |
-| `horizon-parity-main` | parity-main on main | Nothing can be done on GitHub. Nightlies wait for the last commit it passed on |
-| `horizon-nightly`, `horizon-release` | The Nightly's and the launcher's macOS builds | Nothing can be done on GitHub. No Nightly or launcher release until the Mac is back |
-
-What keeps working without them: `verify` and merging, triage and labels (once `SELF_HOSTED_CI=off`), Kira, the
-website, the mods registry and its checks, the official server.
-
-What the council decides about it (which pull requests may still merge without the vanilla harnesses, and who could
-host a runner with their own Minecraft) is a poll, not a rule on this page.

-## Mojang republished the version

-The hourly `mojang republish` workflow opens an issue "Mojang republished 26.3: <hash>" when Mojang changes the
-version file the game is pinned to. If its text says the jars are unchanged, a pull request that pastes the snippet
-from the issue into `research-lock.json` fixes it. New players can't prepare the game until a Nightly with that fix
-is out, so label that pull request `release-now` (or ask the council to) once it merged.
-
-## The mods registry (horizon-rust/horizon-mods)
-
-- **Submissions from the website** arrive as pull requests authored by `ludovic111` (the registry's account). A
-  Team member reviews the mod (what it does, its licence, no sign-in or token handling, no Mojang files; see
-  `MOD-POLICY.md` there), approves, and squash-merges once `check` passed. Publishing to the registry is hourly
-  (`publish.yml`).
-- **Fork pull requests:** approve their workflow run, and upload the mod's file to the `staging` release as
-  `<sha256>.<extension>` after checking its hash.
-- **Taking a mod down:** a pull request adding it to `revoked.toml`. That file is a code-owner path: today only
-  Ludovic can approve it. For malware, two council members act at once as an emergency (GOVERNANCE.md 4.6), post
-  in #mod-log, and ask Ludovic to approve.
-
-## Kira
-
-Kira runs on Railway and needs nobody's machine.
-
-- **Questions Kira can't answer** ("passed to the team") are listed in #kira-handoffs. Answer the member in their
-  thread.
-- **Switches anyone on staff can use:** `/kira-ai off|on` (AI answers), the triage pause.
-- **Polls:** `/vote question:` (council members) starts a 24-hour poll; `/poll start` for the other kinds. The
-  results are in #polls-and-decisions and in `https://kira-production-500e.up.railway.app/decisions.json`.
-- **If Kira is down:** only the account holder can reach Railway today. Post in #council so someone tells him.
-
-## The official server
-
-The server (play.playhorizon.dev) runs on its host's panel, not on the maintainer's machines, and keeps running the
-engine it has. Engine updates, backups and disk clean-ups are done by people with panel access; who has it, and the
-steps, are in the council's private notes. Players' reports go to #mod-chat as usual. If the server is down, a
-council member tells the panel holders and the host.
-
-## Security problems
-
-- **Reports** come through GitHub's private vulnerability reporting ([security.md](security.md#reporting-a-security-problem)).
-- **A leaked secret, a malicious pull request or mod, a hijacked account:** any two council members act at once
-  (GOVERNANCE.md 4.6): label an issue `release-blocker` to stop Nightlies, `/nightly clear` the picks, close the pull
-  request, take the mod down, remove the account's roles, and ask the account holder to rotate the secret. Record it
-  with `/emergency` in Kira once that command exists, else in #council.
-
-## Who to ask
-
-- Code and merges: the Horizon Team, in #horizon-team.
-- Decisions: the council, by poll.
-- Accounts (GitHub organisation, Discord ownership, Railway, the server panel, domains): the account holders; the
-  list is in GOVERNANCE.md section 11.

+## Pad capture
+
+Several overlays over play take the controller for themselves. `Game::pad_capture`
+(`crates/horizon-client/src/game/pad/capture.rs`) is the one place that says which owns it now,
+in one priority order:
+
+| `PadCapture` | Owns the pad while |
+|---|---|
+| `Keyboard` | the on-screen keyboard is up |
+| `Prompt` | a prompt is over the world (a server dialog, the code of conduct, a link, command or resource pack prompt) |
+| `Radial` | the radial menu is held open |
+
+Code that routes the pad's presses and sticks (`pad.rs`, `pad_actions.rs`, `pad_menu.rs`,
+`window_handler.rs`), and the controller guide, which gives way to the keyboard, ask
+`pad_radial_captures()` or `pad_keyboard_captures()` rather than the overlays themselves. A new
+overlay that takes the pad adds its variant here, in its place in the order, and a check that asks
+about it gets a `pad_<overlay>_captures()` beside these. What vanilla draws under an overlay gives
+way through `overlay_holds_view` instead ([Overlays that hold the view](#overlays-that-hold-the-view)).
+Screens are not overlays: `pad_in_menu` says when one has the pad.
+
+One change came with it: a prompt that arrives while the radial menu is open owns the pad from that
+poll, so a B in the same poll answers the prompt instead of cancelling the menu (which the prompt
+closes anyway). Before, the menu took that B.
