Quick HTML testing with RubyMine

If you need to test some HTML, e.g. an embed code, you can use RubyMine's "scratch files":

1. File > New Scratch File (or Ctrl + Shift + Alt + Ins)
2. Select "HTML" as file type
3. Write or paste the HTML
4. Move your mouse to the upper right corner of the scratch file editor. Pick a browser to instantly open your file.
