Desktop app: keyboard shortcut to switch between conversations

Feature Request

The Claude desktop app has no keyboard shortcut to switch between open conversations. Currently the only way to navigate between chats is clicking in the sidebar.

Suggested Shortcuts

• Cmd+Shift+] / Cmd+Shift+[ — next/previous conversation (matches Safari/Chrome tab switching)
• Or Cmd+Option+Down / Cmd+Option+Up — next/previous conversation

Why

When running multiple conversations in parallel (e.g. one for coding, one for research, one background task), switching between them requires mouse interaction every time. A keyboard shortcut would make multitasking significantly smoother — especially for power users who stay on the keyboard.

Context

• Verified the app has no existing menu items for conversation navigation (checked Electron menu definitions in app.asar)
• macOS system keyboard shortcuts can't help since there are no menu items to bind to
• This is a common pattern in tabbed interfaces (browsers, IDEs, terminal apps all support it)
