## Summary [@milanglacier reported in #28653](https://github.com/openai/codex/issues/28653) that the active mention candidate is hard to distinguish. I suspect [@binbjz’s #28500 report](https://github.com/openai/codex/issues/28500) _(where arrow-key navigation appeared not to work)_ may describe the same presentation problem: the selection may have been changing, but the UI was not showing the active row clearly in their terminal. This PR makes two small changes to the selection indication behavior: - Reserve a two-character gutter and mark the active candidate with `> ` for color-agnostic indicator coverage. - Apply the shared theme-aware accent to the entire selected row for extra emphasis. - Update the existing popup snapshot. Reverse-video styling was considered, but avoided it because it is overly dependent on the user’s terminal palette. <img width="2046" height="482" alt="image" src="https://github.com/user-attachments/assets/b5eb62c3-fd24-4c09-906e-7bd66913b5c6" /> ## Testing - `just test -p codex-tui default_unified_mention_popup_snapshot` - `just clippy -p codex-tui` - `just fmt` - Compiled `codex-cli` and tested the unified mentions picker in the terminal.
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.
