Summary

Ctrl-B triggers “Toggle Sidebar” instead of moving the cursor backward in text inputs. Cmd-B also triggers “Toggle Sidebar”.

Actual behavior

• When focus is in the prompt input textarea, pressing Ctrl-B toggles the sidebar (instead of moving the cursor backward).

Impact

On macOS, Ctrl-B is a standard text-editing shortcut (move cursor backward) in text fields. Capturing it at the app level breaks expected editing behavior (especially for users who rely on Emacs-style shortcuts).

What steps can reproduce the bug?

1. Open the Codex app on macOS.
2. Click into a textarea so the caret is visible.
3. Press Ctrl-B.
4. Observe the sidebar toggles.
5. Press Cmd-B.
6. Observe the sidebar toggles as well.

Reproducibility: 100% (always)

What is the expected behavior?

• When focus is in a text input/textarea, Ctrl-B should perform the default macOS behavior: move the cursor backward by one character.
• App-level shortcuts (e.g., Toggle Sidebar) should not override standard text-editing shortcuts while typing in text fields.
