Hello Nicholas, Thanks so much for your answer! Here's what I get when I use printf '\033[>4;2m' then cat...
*In iTerm2* • Press Control + Shift + H → ^[[27;6;72~ • Press Control + Shift + L → ^[[27;6;76~ • Press Control + C → ^[[27;5;99~ (instead of interrupting cat 🤔) *In Ghostty* • Press Control + Shift + H → ^[[27;5;72~ • Press Control + Shift + L → ^[[27;5;76~ • Press Control + C → ^C (interrupts cat) So based on what you said, iTerm2 behaves like Xterm while Ghostty doesn't. I'll reach out to Ghostty's authors. Grégory PS: Is there a name for printf '\033[>4;2m'?
