How to set up shortcut keys to send to AI in Cursor

How do I set a shortcut key to submit cursor content to the chat? I don’t like using Enter to send commands, as I often mistakenly send unfinished text to the AI when I use Shift+Enter for line breaks in long texts. Where can I set the shortcut key command to send to the AI, for example, I’d like to set it to Alt+Enter to send commands to the AI.
