+## Command Line Style Prompt History Navigation
+
+Navigate your prompt history with a terminal-like experience using the arrow keys. This feature makes it easy to reuse and refine previous prompts, whether from your current conversation or past tasks.
+
+### Key Features
+- **Up/Down Arrows**: Cycle through previous prompts.
+- **Context-Aware**: Switches between conversation and task history.
+- **Preserves Input**: Remembers what you were typing.
+
+### Why This Matters
+
+**Before**: Reusing a prompt meant scrolling up, copying, and pasting.
+- Tedious and slow
+- Easy to lose your place
+- Interrupted your workflow
+
+**With Prompt History Navigation**: Quickly access past prompts without leaving the keyboard.
+
+### How it Works
+
+The navigation is designed to be intuitive and adapt to your current context.
+
+#### In an Active Conversation
+- **Arrow Up**: Shows the last prompt you sent. Keep pressing to go further back in the conversation.
+- **Arrow Down**: Moves forward through the conversation history, eventually returning to the text you were typing.
+
+#### Starting a New Chat
+- **Arrow Up**: Shows the most recent prompt from your task history in the current workspace.
+- **Arrow Down**: Moves forward through your task history.
+
+#### Edge Cases
+- If you start typing while navigating, the history is dismissed, and your new text is preserved.
+- Navigation only works when your cursor is on the first or last line of the input box to avoid interfering with multi-line editing.
+
+### Configuration
+
+This feature is enabled by default. There are no settings to configure.
+
+### Benefits
+
+- **Faster Workflow**: Reuse prompts without using the mouse.
+- **Better Context**: Easily access and build upon previous interactions.
+- **Less Interruption**: Stay focused on the task at hand.
+
+### Common Questions
+
+**"Why doesn't anything happen when I press the up arrow?"**
+- You might be in the middle of a multi-line prompt. The cursor must be on the first line.
+- There might be no history available for the current context.
+
+**"What's the difference between conversation and task history?"**
+- **Conversation history** includes prompts from your current, active chat session.
+- **Task history** includes the initial prompts from all previous tasks in your current workspace.
