Feature request: keyboard shortcut to jump between messages in conversation

Feature request: jump/navigate between messages in the conversation

In long sessions there's no way to quickly move between messages in the transcript. Up/Down only recall previous input prompts; there's no shortcut to jump to the previous/next user message (or turn) in the conversation view.

Requesting

• Keyboard shortcut to jump to previous/next user message (e.g. Ctrl+Up / Ctrl+Down or Alt+Up / Alt+Down).
• Optionally jump between turn boundaries (user + assistant reply) rather than every tool block.
• Bindable via ~/.claude/keybindings.json.

Applies to

• VS Code extension
• Terminal CLI

Current workaround

Only Cmd+F search, which is slow when you just want to step back through your own messages.
