title: Retrieve selected elements in GeckoWebBrowser
body: <p>I am using GeckoFX version 1.9.1.0 with C#.NET. I have a placed a GeckoWebBrowser Component (geckoWebBrowser1) and a Button (button1) in a form and have navigated the browser to a page. Some text in the page can be selected. This text is composed of one or more DOM elements.
  When button1 is clicked, I want to retrieve the DOM elements that compose the selected text in the page and give an id to one of those elements and save add these ids to a list (in C# space).
  How can I do this?</p>
