The Preview and Edit entries do the same thing as the corresponding links. The two following entries will copy either an url or the file path to the clipboard, for pasting into another application.
The More like this entry will select a number of relevant term from the current document and enter them into the simple search field. You can then start a simple search, with a good chance of finding documents related to the current result.
