## View code in the web-based Visual Studio Code

You can open `Visual Studio Code` from your browser to view code in a rich UI. To use it, press the `.` key on any repository or pull request.

For more detailed usage, refer to [github/dev](<https://github.com/github/dev>).

## Check out the branch of a pull request quickly

If you want to check out the branch of a pull request, it's generally troublesome with the fork-and-pull model.

```bash
# Copy the user name and the fork URL.
git remote add {user-name} {fork-url}
git checkout {user-name}/{branch-name}
git remote rm {user-name} # To clean up
```

Instead, you can use [GitHub CLI](<https://cli.github.com/>) to simplify the steps, just run `gh pr checkout {pr-number}`.

You can copy the command from the top right of the pull request page.
