You can drag and drop files onto a Konsole (or Yakuake) terminal session, and it works -- the file is copied to your current directory! That is pretty cool. I just had the situation when I needed to copy a file from an email (in KMail) into the current directory I was in, and I was very chuffed that the drag and drop operation I instinctively went for worked just as planned. It pops up a little menu so you can choose between 'Paste' (the filename) 'cp', 'cd', 'ln' and 'mv'.
