-3. **Navigation between sessions**: When subagents create their own child sessions, you can navigate between the parent session and all child sessions using:
-   - **\<Leader>+Right** (or your configured `session_child_cycle` keybind) to cycle forward through parent → child1 → child2 → ... → parent
-   - **\<Leader>+Left** (or your configured `session_child_cycle_reverse` keybind) to cycle backward through parent ← child1 ← child2 ← ... ← parent
+3. **Navigation between sessions**: When subagents create child sessions, use `session_child_first` (default: **\<Leader>+Down**) to enter the first child session from the parent.
 
-   This allows you to seamlessly switch between the main conversation and specialized subagent work.
+4. Once you are in a child session, use:
+   - `session_child_cycle` (default: **Right**) to cycle to the next child session
+   - `session_child_cycle_reverse` (default: **Left**) to cycle to the previous child session
+   - `session_parent` (default: **Up**) to return to the parent session
+
+   This lets you switch between the main conversation and specialized subagent work.

 You don't need to use a leader key for your keybinds but we recommend doing so.
 
+Some navigation keybinds intentionally do not use the leader key by default. For subagent sessions, the defaults are `session_child_first` = `\<leader>down`, `session_child_cycle` = `right`, `session_child_cycle_reverse` = `left`, and `session_parent` = `up`.
