Enter for newline, Ctrl+Enter to submit

All of these LLM chat interfaces use Shift+Enter for newline and Enter for submit and it’s really annoying when trying to enter multi-line text. I trigger the submit accidentally all the time. It would be nice if Enter was newline and Ctrl+Enter was submit, by default, but an option to choose that would be good, too.

There must be a keybinding setting to change this. I looked and couldn’t find anything. Bueller ?
