Right sidebar
The right sidebar holds the panels you work with next to the document. A tab strip at the top switches between them; the tabs show icons, and the active tab its name.
In the sidebar’s top-right corner:
- Detach panel — opens the Tests, Agent, or Findings panel in a separate window. Attach panel puts it back.
- › (Collapse right sidebar) — hides the sidebar; Expand right sidebar brings it back.
