Description

In Codex Desktop, when I use /MCP to view the configured MCP servers, a secondary menu/popup is displayed with the MCP server list and status information.

I want to exit this UI and return to the normal input/task flow. Currently, the only way to close this UI appears to be clicking the Close button in the top-right corner. Pressing the ESC key does not close the popup/menu.

This feels inconsistent with common desktop UI behavior, where ESC is typically expected to dismiss temporary popups, modal-like panels, dropdowns, or secondary menus.

Environment

• Codex Desktop version: 26.422.30944 (2080)
• OS: macOS 15.7.4 (24G517)
• Chip: Apple M1 Pro

Steps to reproduce

1. Open Codex Desktop.
2. Use the /MCP command to view MCP server status.
3. The MCP server list appears in a secondary popup/menu.
4. Press the ESC key.

Actual behavior

Pressing ESC does not close the MCP popup/menu.

The user must manually click the Close button in the top-right corner to dismiss it.

Expected behavior

Pressing ESC should close/dismiss the MCP popup/menu and return focus to the main input area.

Why this matters

This would improve keyboard navigation and make the UI feel more consistent with standard desktop interaction patterns. It is especially useful when quickly checking MCP server status and returning to the main task without leaving the keyboard.
