- What it is
- OpenAI's official list of Codex configuration keys. It includes a features.in_app_dictation switch for the Codex desktop app. It has no voice or push-to-talk key for the command-line tool.
- How much weight it carries
- Official OpenAI documentation, read on 2026-10-17. Third-party blogs describe spacebar push-to-talk in the Codex command-line tool, but those reports conflict and this reference does not confirm them, so this guide does not rely on them.
Facts taken from this source
- OpenAI's Codex configuration has a features.in_app_dictation setting that turns off dictation in the Codex desktop app.
