+3. **Navigation between sessions**: When subagents create their own child sessions, you can navigate between the parent session and all child sessions using:
+
+   - **Ctrl+Right** (or your configured `session_child_cycle` keybind) to cycle forward through parent → child1 → child2 → ... → parent
+   - **Ctrl+Left** (or your configured `session_child_cycle_reverse` keybind) to cycle backward through parent ← child1 ← child2 ← ... ← parent
+
+   This allows you to seamlessly switch between the main conversation and specialized subagent work.
