Summary

In Warp (macOS), several modified keys are emitted as plain control codes, causing keybind mismatches in OpenTUI consumers.

Capture Method

node -e "process.stdin.setRawMode(true); process.stdin.on('data', d => { if (d[0] === 3) process.exit(); console.log('Len:', d.length, 'Hex:', d.toString('hex'), 'Raw:', JSON.stringify(d.toString())) })"

Observed (macOS)

Ghostty (reference)

Shift+Enter -> 1b5b32373b323b31337e (\x1b[27;2;13~)
Alt/Option+Backspace -> 1b7f (\x1b\x7f)
Cmd+Backspace -> 15 (\x15)

Warp

Shift+Enter -> 0a (\n, linefeed)
Alt/Option+Backspace -> 17 (\x17, same as Ctrl+W)
Cmd+Backspace -> 15 (\x15, same as Ctrl+U)

Impact

Keybinds relying on modifier metadata may not trigger as expected in Warp.
