Keyboard Navigation, Focus, and Selection

Scheduler supports keyboard navigation for headers, cells, and event items. Use the built-in focus and selection behavior for keyboard workflows; use hit testing when a pointer command must identify a Scheduler target.

Navigate with the keyboard

Key or action	Result
`Tab`	Header -> Cell -> Item -> outside Scheduler
`Shift+Tab`	Reverse order: outside Scheduler -> Item -> Cell -> Header
Click a Cell or Item	Makes that element the active focus target

Stages that are not present are skipped.

When a cell has focus, the arrow keys move to the visually adjacent cell. Navigation follows the rendered cell layout regardless of the view type or whether the time axis is on rows or columns.

Navigate event items

Layout	Within current section	Across sections
Timed, hour axis on columns	Left/Right moves between items in the current section	Up/Down moves to the previous or next section that contains items and focuses its first item
Timed, hour axis on rows	Up/Down moves between items in the current section	Left/Right moves to the previous or next section that contains items and focuses its first item
Summary	Up/Down moves between items in the current cell in rendered order. Moving past the first or last item focuses the nearest cell in the same column that contains items.	Left/Right moves to the previous or next cell in the same row that contains items. The target item uses the same rendered index when available; otherwise the last item in that cell is focused.

Items are visited in rendered order. If no target exists, focus remains on the current item.

Focus after CRUD operations

Operation	Focus target after completion
Cancel editor	Cell or item that opened the editor
Save new event	Newly rendered item
Save existing event	Edited item, if still available
Delete event	Previous item in the section; next item if the deleted item was first. If the section has no items left, focus moves to the first cell.
New event falls outside the current view after saving	Cell that was used to create the event
Edited event is no longer available after saving	Same fallback as deleting an event

Select cells

Selection applies to cells, not event items.

Action	Selection behavior
Click a cell	Starts a new single-cell selection
Shift+Click	Extends from the active anchor when resource context matches
Drag across cells	Selects cells after the drag threshold is reached
Release pointer	Ends drag selection and focuses the last selected cell
Pointer reaches viewport edge	Scheduler scrolls and continues extending the selection
Shift+Arrow	Extends selection while moving the cell focus target
Arrow without Shift	Starts a new single-cell selection

A selected range contains only cells that use the same resources.

Selection and context menus

Opening a context menu inside the current selection preserves the selected range. Shift+Right-click can extend the selection to a target cell in the same resource. Opening the menu outside the current selection starts a new selection at that cell.
