This updates the ctrl + c behavior to clear the current prompt if there is text and you press ctrl + c. I also updated the ctrl + c hint text to show `^c to interrupt` instead of `^c to quit` if there is an active conversation. Two things I don't love: 1. You can currently interrupt a conversation with escape or ctrl + c (not related to this PR and maybe fine) 2. The bottom row hint text always says `^c to quit` but this PR doesn't really make that worse. https://github.com/user-attachments/assets/6eddadec-0d84-4fa7-abcb-d6f5a04e5748 Fixes https://github.com/openai/codex/issues/3126
