macOS Turkish keyboard: @ and $ shortcuts are intercepted in Codex

Summary

On macOS with the Turkish keyboard layout, the native shortcuts used to type @ and $ cannot be entered in Codex:

• Command + Q for @
• Option + 4 for $

The same keyboard shortcuts work correctly in Claude.

Expected behavior

Codex should pass these keyboard-layout input combinations through as text, producing @ and $, rather than handling or intercepting them as application shortcuts.

Actual behavior

The characters cannot be typed with the Turkish keyboard layout in Codex.

Environment

• Platform: macOS
• Keyboard layout: Turkish
• Affected characters: @, $

This is especially disruptive because @ is commonly required for mentions, paths, and other input.
