You known when you hover a keyword or class and an info popup is shown.
Press F2 to lock the info popup and you are able to scroll it
content. How does one do that? Thanks.

Got it! Installing an ITextHover to the editor using the internal class
org.eclipse.jface.internal.text.html.BrowserInformationContr ol will do.
The AbstractTextEditor class will respond when 'F2' is pressed but it
does not create the BrowserInformationControl rather an HTMLTextPresenter.
