## Why Closes #25006. `tui.keymap` currently rejects `F13` even though Codex's terminal event layer can report higher function keys. This prevents users from using common remappings such as Caps Lock to `F13`. ## What Changed - Define a shared portable upper bound of `F24` for stored TUI keybindings. - Accept `f13` through `f24` in config normalization and runtime parsing. - Allow `/keymap` capture to persist `F13` through `F24`. - Update the unsupported-function-key error and add boundary tests for `F13`, `F24`, and `F25`. ## How to Test 1. Add a binding such as: ```toml [tui.keymap.global] open_transcript = "f13" ``` 2. Start Codex and press the remapped `F13` key. 3. Confirm Codex loads the config without the previous `F1 through F12` error and the action runs. 4. Open `/keymap`, capture `F13` for an action, and confirm the saved binding is `f13`. 5. As a regression check, try to capture `F25` and confirm Codex reports that only `F1` through `F24` can be stored. Targeted tests: - `just test -p codex-config` - `just test -p codex-tui function_keys` Full `just test -p codex-tui` completed with 2,752 passing tests, 4 skipped tests, and two unrelated guardian feature-flag failures: - `app::tests::update_feature_flags_disabling_guardian_clears_review_policy_and_restores_default` - `app::tests::update_feature_flags_disabling_guardian_clears_manual_review_policy_without_history`
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
