Option+Delete (word delete) stopped working in chat input on macOS

Description

Option+Delete (delete word backward) and Cmd+Delete (delete to beginning of line) no longer work in the Claude Code chat input on macOS. These are standard macOS text editing shortcuts that previously worked.

Expected behavior

• Option+Delete should delete the previous word
• Cmd+Delete should delete to the beginning of the line

Actual behavior

Neither shortcut has any effect in the chat input. Holding down modifier keys (Cmd/Option) with Delete does not delete text faster/by word as expected.

Workaround

Ctrl+W (delete word) and Ctrl+U (delete to line start) still work as alternatives.

Environment

• macOS (Darwin 25.3.0)
• Shell: bash
