+# Use The Table Of Contents
+
+The table of contents panel helps you navigate long notes by heading.
+
+## Open It
+
+Use the editor toolbar, the command palette, or the shortcut:
+
+- `Cmd+Shift+T` on macOS.
+- `Ctrl+Shift+T` on Windows and Linux.
+
+## How It Works
+
+HoloLake Era builds the outline from the current note's headings. The panel updates as the note changes and can jump to sections in the editor.
+
+## Good Uses
+
+- Long procedures.
+- Meeting notes with many sections.
+- Research notes.
+- Generated documents that need review.
+
+If a note has no useful headings, add clear H2 and H3 sections rather than relying on a long uninterrupted document.
