## Why Fixes #21046. Codex TUI 0.128.0 can show Backspace/Delete-related editor shortcuts in `/keymap`, but Windows-style modified Backspace/Delete events were still dropped by the composer because the default editor keymap did not include those modified special-key variants. On Windows/CMD this meant `Shift+Backspace` and `Shift+Delete` did not fall through to normal character deletion, and `Ctrl+Backspace` / `Ctrl+Delete` did not perform the word deletion users expect from Windows text inputs. ## What Changed - Added default editor bindings for `shift-backspace` and `shift-delete` so shifted delete keys keep normal grapheme deletion behavior. - Added default editor bindings for `ctrl-backspace`, `ctrl-shift-backspace`, `ctrl-delete`, and `ctrl-shift-delete` so Windows-style word deletion works when terminals preserve those modifiers. - Added regression coverage for the resolved default keymap and textarea behavior. ## How to Test 1. Start Codex in the TUI on Windows CMD or another terminal that reports modified Backspace/Delete keys distinctly. 2. Type `hello world` in the composer. 3. Press `Ctrl+Backspace`; confirm `world` is removed and `hello ` remains. 4. Type `world` again, move the cursor before it, then press `Ctrl+Delete`; confirm the next word is removed. 5. Type a few characters and press `Shift+Backspace` and `Shift+Delete`; confirm they delete one character in the expected direction instead of doing nothing. 6. Open `/keymap`, inspect the Editor deletion actions, and confirm the modified Backspace/Delete aliases are visible as configurable defaults. Targeted tests: - `cargo test -p codex-tui keymap::tests` - `cargo test -p codex-tui bottom_pane::textarea::tests` - `cargo test -p codex-tui keymap_setup::tests`
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.
