Confirmed
Ctrl+Enter is contextual
Inside the annotation editor it saves/queues the current comment depending on mode. It is not a dedicated accelerator for the top toolbar’s batch Send button.

Annotation Submit Research
A source-backed answer to one practical question: how can a browser annotation be submitted without reaching for the blue Send button?
Best Answer
Bind “Send message” to your own key
The installed Codex app exposes Send message as a configurable app-wide command. The blue annotation toolbar’s Send button invokes that same command. It has no default key binding in this build, which is why Ctrl+Enter did not replace the click.
Set It Once
- Press Ctrl+/ to open Codex keyboard shortcuts.
- Search for Send message.
- Assign an unused shortcut—for example Ctrl+Shift+Enter.
- While browser annotations are staged, use that shortcut instead of clicking the blue Send button.
Fallback
Focus, then Enter
The top Send control is a normal button, so keyboard focus plus Enter or Space activates it. This is valid but slower than a custom app-wide binding.
Not Current Proof
Modifier-click guidance
Older and Mac-oriented material mentions Command-click to send immediately. Current OpenAI browser documentation does not publish a Windows equivalent, and the installed flow does not expose that as the reliable no-mouse answer.
Limitation
No UI automation test
The app’s Computer Use safety rules prohibit automating the Codex desktop UI itself. Verification therefore combines current docs with read-only inspection of the installed application package.
Evidence
| Source | What it establishes | Confidence |
|---|---|---|
| Installed Codex app package, build 26.715.2305.0 | composer.submit is shortcut-configurable, has no shipped default binding, and is invoked by the annotation toolbar Send action. | Direct local evidence |
| OpenAI browser documentation | Documents annotation mode and sending the resulting context, but does not list a dedicated annotation Send shortcut. | Current first party |
| OpenAI Help: built-in browser | Confirms the annotation workflow; likewise omits a Send accelerator. | First party |
| User report: annotation behavior change | Corroborates that Ctrl+Enter changed to queue/save behavior on Windows rather than universally dispatching the annotation batch. | Secondary corroboration |
Bottom Line
There is no reliable default one-stroke shortcut for the blue annotation Send button in the installed Windows build. The durable solution is to assign one to Send message in Codex keyboard shortcuts. Recommended first try: Ctrl+Shift+Enter, provided Codex reports no conflict.
