What's Wrong?

Environment

• Client: Claude Desktop app, Code tab
• OS: Windows (x64)
• App version: 1.37937.1
• Connection: local

Summary

In the Code tab, pressing Enter to submit a prompt intermittently stops working — it either inserts a newline or does nothing, and only Ctrl+Enter submits. This is already tracked in #85013 and #44537.

What doesn't seem to be captured yet: this isn't isolated to Enter. When Enter fails to submit, the session list's "..." (kebab) menu simultaneously loses its single-letter shortcuts (e.g. "A" for Archive) — the menu renders without them. When Enter works normally, those shortcuts are visible and functional in the same menu. The two symptoms appear and disappear together, every time, which suggests the app's keyboard-shortcut handling layer as a whole is intermittently failing to initialize or attach for a session, rather than Enter having its own isolated bug.

Steps to reproduce

1. Use Claude Desktop's Code tab normally across a session (or across Remote Control, if applicable).
2. Periodically check: does Enter submit a typed prompt? Does the session's "..." menu show letter shortcuts like "A" for Archive?
3. Observe that both either work together or fail together — never one without the other.

Expected behavior
Enter submits the prompt, and the session menu shows its keyboard shortcuts, consistently.

Actual behavior
Both intermittently stop working at the same time; only Ctrl+Enter and mouse clicks remain functional until (seemingly at random) both come back.

Workaround

• Use Ctrl+Enter to submit when Enter fails.
• Use the mouse to archive (click the archive icon on the row) when the menu shortcut is missing.

Notes

• Editing ~/.claude/keybindings.json (or the Windows equivalent) does not help — the Desktop app doesn't currently read that file at all (see #84101), so this isn't a keybinding-configuration issue.
• Related/possibly duplicate reports: #85013, #44537, #86449, #84101.

What Should Happen?

Expected behavior
Enter submits the prompt, and the session menu shows its keyboard shortcuts, consistently.
