## Why Codex enables enhanced keyboard reporting while the TUI owns the terminal. In iTerm2, exiting the TUI with Ctrl+C can intermittently leave the parent shell receiving raw CSI-u / `modifyOtherKeys` fragments instead of normal key input. Final terminal cleanup should put the parent shell back into normal keyboard reporting even if the terminal misses the usual stack pop. Fixes #19553. ## What Changed - Move TUI keyboard enhancement setup and detection into `tui/src/tui/keyboard_modes.rs`. - Add an exit-only `restore_after_exit()` path that performs the normal keyboard enhancement pop plus unconditional keyboard enhancement and `modifyOtherKeys` resets. - Keep temporary restore paths, such as external-editor handoff, using the balanced stack pop behavior. ## Confidence Medium. This is a speculative fix: I was not able to reproduce the reported iTerm2 behavior manually, but the symptoms line up with terminal keyboard reporting state surviving Codex exit. The added reset sequences are scoped to final TUI shutdown and should be harmless when the terminal is already clean.
npm i -g @openai/codex

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
Install globally with your preferred package manager:
# 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.
