OptionalactivateActivate a task pane by key (the test activateTask command). Threaded from useTaskPaneArea().
OptionaleditableThe shared cell SheetEditable — the insertFunction picker seeds =FN( through it (start an edit
on the active cell if idle, or insert at the focused editor's caret). Functions are a workbook concern
(custom functions live in the workbook's scripts, not any one sheet), so the picker resolves here rather
than on sheet. Omit ⇒ insertFunction stays chrome-only (the category list still shows; inserting no-ops).
OptionalfindPersisted last-search memory (workbook.lastFind), owned by the bridge's usePersistentState. Feeds
findNext / findPrevious and the find window's seed. Omit ⇒ those two stay disabled and the window
always seeds from the active cell.
OptionalfocusFocus the name box (the formula bar's named-range editor). activeNameBox is a workbook command (the
name box is logically part of the workbook surface), but its editor is currently packaged in the studio
formula bar — so the focus is injected as a plain callback (keeps this package free of studio types). This
is a bridge: when the name-box capability gets a react home (chromeless-workbook track), this becomes a
proper imperative handle on IWorkbookElement. Omit ⇒ activeNameBox stays disabled (no name box).
OptionalnotifierBusy / error / dialogs (find, goto, new-style, named-reference).
OptionalthemesTheme collection for the selectTheme picker context. Omit ⇒ the picker has no list to show.
