The reorder shortcut cannot be made reliable in this UI. `Alt + Arrow` is
the browser's tab-history / back-forward gesture on several platforms,
and the modal already binds bare `ArrowLeft`/`ArrowRight` to model
navigation, so the binding either did nothing — a keypress with nothing
focused never reaches a listener on the tag list — or fought the browser.
An affordance that occasionally navigates the page away is worse than
having no keyboard path at all, so drop it.
Reordering is pointer-only again: drag the chip (tags) or its `⠿` grip
(trigger words, whose chip body is click-to-edit). Everything that existed
only to serve the shortcut goes with it — the keydown listener, the hover
tracking used to resolve the target chip, the aria-live announcements, the
per-grip position labels and `moveItemWithinContainer`. The grip becomes a
decorative, non-focusable `<span>` (`aria-hidden`, behind a 5px drag
threshold) instead of a `<button>`, so it no longer promises a keyboard
action it cannot perform.
The tooltip and hint drop the shortcut mention in all 10 locales
(`common.reorder.dragHandle` = "Drag to reorder" and the localised
equivalents); `common.reorder.ariaLabel` and `common.reorder.announcement`
are pruned from every locale by the sync script. The i18n guidelines
record the decision so no shortcut is re-added without re-adding the keys.
Model tags could already be reordered by dragging a chip, but the only
hint was a `cursor: grab` on `.metadata-item` — a hover-only, mouse-only
signal that also leaked into the bulk add-tags modal, where the chips are
not sortable at all. Trigger words could not be reordered, and their
order matters: "Copy Trigger Words" and the insert-into-node action join
the array as-is to build a prompt.
Both editors now share one vocabulary: a `⠿` grip that appears whenever
the list has something to order, plus `Alt + arrow` keyboard moves with
an aria-live announcement. Whether the chip body is draggable is a
property of the item rather than of the feature:
- tags have no click action of their own, so the whole chip stays
draggable (`handleSelector: null`), with a 5px threshold so a click on
the grip only focuses it
- trigger words keep click-to-edit on the body, so a drag starts from the
grip only
- the grip is the element that opts out of touch scrolling
(`touch-action: none`), so touch users drag by the grip in both editors
- reordering is offered only while editing: trigger words reveal the grip
from `.edit-mode`, tags from the edit container, which stays hidden
outside edit mode
The drag engine moves out of ModelTags.js into shared/pointerSort.js,
which now marks sortable containers with `pointer-sort-enabled` so only
lists that really sort show the grab cursor. Labels, the sortable flag,
the keyboard handler and the live region live in
shared/reorderSupport.js, and both editors render the same three
`common.reorder.*` keys (translations follow in the next commit).
Two inherited engine bugs are fixed on the way: the drop position was
only settled when an animation frame was still pending, so a fast drag
(or one that started by crossing the threshold) fell back into its
original slot; and the guard that stops a drop from triggering the chip's
own click handler was removed on a timer, swallowing unrelated clicks
until the next task.
