Navigate collapsed Document content

Choose Find to search authored text, or Outline to jump to a heading. When a destination is inside one or more collapsed toggles, Document temporarily reveals those containers so the selected text or heading is visible. This works in editable and read-only Documents. Other collapsed containers stay closed.

The reveal changes the view, not the authored document. It does not change a toggle's stored open state, create a save, or add an Undo/Redo entry. Closing Find/Outline, choosing another tool, suspending the surface or changing its owner removes the temporary reveal. A suspended Find retains its query; select the next match again after resuming to reveal that target.

Closing Find or Outline with Close or Escape returns the caret to visible text outside a section that collapses again. It skips other closed containers; typing cannot replace the now-hidden match. If every text position is collapsed, focus returns to Find (or the App's Document options control) instead of the editor. Closing alone still creates no document save or Undo step.

Use a revealed container's Collapse toggle button to dismiss its temporary reveal. If the container was already open before navigation, deliberate toggle controls retain their normal authored/read-only behavior. Navigation does not rewrite content, evaluate embedded model values, or change recovery authority. Find retains its existing literal-text, match-case and replacement limits.

Follow the collapsed-content walkthrough. Dense native opening remains an open performance gap; navigation keeps the full native document and its existing writer.
