VS Code: Add a slash command / hot key for creating a new chat

What variant of Codex are you using?

VS Code extension

What feature would you like to see?

Currently AFAIK the only way to start a new chat in the VS Code extension is to click the "New Chat" icon in the top right (or hit the back button). What would be nice is a hot key or slash command to create a new chat via keyboard so we don't have to reach for our mouse every time.
