"Action" is either a function or a URL to open. "Class" is the class given to the icon. "Tooltip" is the small tooltip that appears via the `title=""` attribute. The `Ctrl` and `Alt` in the title tags will be changed automatically to their Mac equivalents when needed. Additionally, you can add a separator between any icons by adding `"|"` to the toolbar array.
