# ChromeVox Debugging on Chromebook

This skill provides instructions and scripts for toggling ChromeVox and
injecting key events into standard ChromeOS devices over SSH.

## 1. Toggling ChromeVox

You can run the bundled Python script on the targeted device to toggle ChromeVox
by simulating a `Ctrl+Alt+Z` keyboard shortcut.

Save or copy
`agents/skills/chromevox-debugging-on-chromebook/scripts/toggle_chromevox.py` to
`/tmp/toggle_chromevox.py` on the device. Then execute it via SSH:

```bash
ssh -p 2222 -i third_party/chromite/ssh_keys/testing_rsa root@localhost "python3 /tmp/toggle_chromevox.py /dev/input/event5"
```

> [!NOTE] Replace `/dev/input/event5` with the correct keyboard input device
> node. You can find the keyboard node on the device by running:
> `python3 -c "import evdev; [print(evdev.InputDevice(path).name, path) for path in evdev.list_devices()]"`

## 2. Sending Custom Key Events

If you need to inject specific keys into the system, save or copy
`agents/skills/chromevox-debugging-on-chromebook/scripts/send_key.py` to
`/tmp/send_key.py` on the device.

Execute it specifying the device node and key code (e.g., `44` for `KEY_Z`):

```bash
ssh -p 2222 -i third_party/chromite/ssh_keys/testing_rsa root@localhost "python3 /tmp/send_key.py /dev/input/event5 44"
```
