## Accelerators

`Accelerator::parse('Primary+Shift+F5')`: modifier tokens, then one key token, `+` between, any case.[^accelerator] Modifiers: `Primary` (Command on macOS, Control elsewhere), `Ctrl`, `Alt` (Option on macOS), `Shift`, `Meta` (Command on macOS, Super elsewhere); `command()` / `control()` / `super()` resolve them per platform. Keys: letters, digits, punctuation (`MINUS` … `SLASH`), `F1`-`F12`, arrows, `HOME`, `END`, `PAGE_UP`, `PAGE_DOWN`, `SPACE`, `ENTER`, `TAB`, `ESCAPE`, `BACKSPACE`, `DELETE`; by `Key` case name or by the character typed without Shift (`]` = `RIGHT_BRACKET`). Other keys throw (`INSERT`: AppKit cannot choose an item from the Help key a Mac reads for Insert). A key other than `F1`-`F12` needs `Primary`, `Ctrl`, `Alt` or `Meta`. Two items with the same accelerator on macOS or elsewhere throw; each edit role holds its standard one (`Primary+Z`, `Primary+Shift+Z`, `Primary+X`, `Primary+C`, `Primary+V`, `Primary+A`). An enabled accelerator gets its key before the focused widget, on all toolkits.

Exclude edit roles from the general accelerator rule.

GTK and Qt edit roles use the focused widget's action and have no accelerator. AppKit edit roles use the standard key equivalents. Update the final sentence so it applies only to non-edit accelerators.

Suggested clarification 
-... An enabled accelerator gets its key before the focused widget, on all toolkits.
+... Non-edit enabled accelerators get their key before the focused widget on all toolkits. Edit roles use toolkit-specific behavior: AppKit uses standard key equivalents; GTK and Qt use the focused widget's action without an accelerator.

## Enabled state

`$window->setItemEnabled($id, false)` / `isItemEnabled($id)`; the default bar: `ToolkitWindowManager::setItemEnabled()` (gives the driver the default profile first). No rebuild, no mail. A node is effectively enabled when it and every folder above it are enabled; the rest show disabled, post nothing, and their accelerators do nothing. `isItemEnabled()` = own state; it throws, as `setItemEnabled()` does, for an edit role, a folder holding one and the first folder (the toolkit owns those). `MenuStates` holds both for drivers and fakes; `changes()` = the states that differ from the profile, which a bar built later replays.[^states] `enabled` must be a bool; `keys` a string or an `Accelerator`; a separator takes no other key. A new profile (`setMenuBar`, another default) starts from its own states.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Document the code-cancellation exception for CanvasReleased.

surface/architecture/toolkit-primitives.md, Line 127 states that watchPointer(false), disabling or removing the canvas, and window close drop the press without mail. Therefore, “exactly one per CanvasPressed” is not true for those cases. Add this exception so consumers do not wait for a release that never arrives.

Clarify when WindowKeyPressed is posted.

Line 14 contains “a key press no focused native,” which is not grammatical and does not state that the focused native control failed to handle the key. Describe the event as posting only after the accelerator, default/cancel, Tab, and focused-native checks do not handle the key.

A link's URL needs a scheme (WindowException otherwise, before the native exists or changes); the toolkit opens it on a click and nothing posts.

* Dropdown: `selected` = -1 exactly when no options; `setOptions` keeps an in-range selection else 0.
* Table: rows normalised to every column in column order, missing key `''`; `setRows`/`clearRows` clear selection; `appendRow` keeps it; every reload re-applies the selection.
* Tree: ids unique across the forest (`WindowException`, nothing changed). Expansion recorded in Surface, nodes with children only; kept while an ancestor is collapsed, re-applied by `reopen()` when it opens. `expand()` on a leaf = no-op. `setNodes` keeps expansion and selection for ids still present; a kept selection now under a collapsed node opens its ancestors, as `selectNode()` does. Selection read from the native.

Focus: every primitive has `focus()` (throws `WindowException` when removed, hidden or disabled itself or through a container, or when the native declines; the native is not asked in those cases) and `hasFocus()`, through the abstract hooks `applyFocus(): bool` and `nativeHasFocus()`; the driver focuses the native's focus target (the inner view of a scroll-wrapped native).

Complete the takesTab condition.

The sentence ends at “whenever focusable is”. State the missing condition explicitly, for example: “takesTab is false whenever focusable is false.” The current wording leaves the setFocusable() contract ambiguous.

Pointer: `watchPointer(bool $on = true)` / `isWatchingPointer()`. Off by default; the flag lives in the abstract and nothing is written to the native (as a context menu is not) — the window's pointer source reads it. `watchPointer()` throws `WindowException` once the canvas is removed. While watching, the canvas posts `CanvasPressed`, `CanvasDragged`, `CanvasReleased` and `CanvasWheeled` ([view mail](/docs/{{version}}/surface/api/view-mail)) in points from its top-left, as `CanvasClicked`'s. `CanvasClicked` and the right-click rules post either way, so a sketch that wants only clicks never watches.

* One press at a time per window: the first button down on a watching, enabled canvas owns it; other buttons' presses and releases post nothing until it ends. `CanvasDragged` posts per move while that button is held, only when the point changed, and goes on outside the canvas and the window (implicit capture).
* Exactly one `CanvasReleased` per `CanvasPressed`: at the owning button's release, or at once at the last point posted when the toolkit ends the press without one (a context menu opens, GTK's grab breaks, a touch is cancelled). A press ended from code — `watchPointer(false)`, the canvas or a group above it disabled, `remove()`, the window closed — drops silently, as no mail comes from code.
* A toolkit-emulated touch is the left button. `clicks` counts presses of the same button on the same canvas within the toolkit's double-click time and distance, so a triple click is 3 everywhere.
* A wheel over a watching, enabled canvas is the canvas's: posted and not passed on, so an enclosing scroll view stays put. Not watching, it passes as before.

Surface lending: `TKCanvas` is a `WindowOutput` (`Surface\Contracts\Drawing`). A GPU engine borrows a native surface inside the canvas instead of drawing into its framebuffer.

* `surfaces()`: `[]` until a toolkit's canvas overrides it, with `makeSurface(kind, handles): array` (the surface's handles by name, always `kind->handle()`) and `removeSurface(kind)`. Both have default bodies.
