18.1.1 Browser Controller Objects

Browser controllers provide two methods which parallel two of the module-level convenience functions:

`open`( | url[, new[, autoraise=1]])

  Display url using the browser handled by this controller. If new is 1, a new browser window is opened if possible. If new is 2, a new browser page ("tab") is opened if possible.

`open_new`( | url)

  Open url in a new window of the browser handled by this controller, if possible, otherwise, open url in the only browser window. Alias `open_new`.

`open_new_tab`( | url)

  Open url in a new page ("tab") of the browser handled by this controller, if possible, otherwise equivalent to `open_new`. New in version 2.5.
