fix: forward Cmd+Delete and Option+Delete to PTY#92
Merged
Conversation
Cmd+Backspace now sends ^U (kill-line-to-beginning) and Option+Backspace sends ESC+DEL (backward-kill-word), matching macOS text-field conventions and what bash/zsh/Claude Code's input field interpret. Previously these key combos fell through to SwiftTerm, which forwarded a plain DEL byte for both — so neither shortcut did anything useful. Option-modified keys skip performKeyEquivalent entirely, so the existing keyDown monitor (already used for paste) is the only reliable place to intercept them.

Cmd+Delete and Option+Delete wrote directly to the PTY without checking handlesPasteShortcuts, so they could escape the 0.3s startup keystroke suppression window (which exists so stray keys don't corrupt a new Claude tab's pending initial command). Hoist the handlesPasteShortcuts gate to cover all input shortcuts, matching the existing paste behavior. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
