title: Delphi IDE: Keyboard shortcut to duplicate current line or selection?
body: <p>Many even simple editors (e.g. Notepad++ or RubyMine) have this: pressing Ctrl+D duplicates the current selection or the current line if nothing is selected. </p>
  
  <p>Is there any shortcut like that in the Delphi IDE (2010 or XE2)? I read through the various short cut lists, but didn't find anything.</p>
