Enter inserts a newline. Ctrl/Cmd+Enter sends.
A lot of chat sites send the message as soon as you press Enter. DeepSeek is the worst offender, and it has no setting to change it. So when you only wanted to start a new line, you end up sending a message you weren't done with.
Enter Guard flips that. Now Enter gives you a newline, and Ctrl/⌘+Enter sends when you're actually ready.
No problem. The Enter that confirms a pinyin or IME candidate is never touched.
