-// Jürgen, note that this means that you cannot currently have a list
-// of selections cut/copied. So IMHO later we should have a
-// list/vector/deque that we could store
-// struct selection_item {
-// Paragraph * buf;
-// LyXTextClassList::size_type textclass;
-// };
-// in and some method of choosing beween them (based on the first few chars
-// in the selection probably.) This would be a nice feature and quite
-// easy to implement. (Lgb)
-//
-// Sure but I just cleaned up this code for now with the same functionality
-// as before. I also want to add a XClipboard function so that we can copy
-// text from LyX to some other X-application in the form of ASCII or in the
-// form of LaTeX (or Docbook depending on the document-class!). Think how nice
-// it could be to select a math-inset do a "Copy to X-Clipboard as LaTeX" and
-// then do a middle mouse button click in the application you want and have
-// the whole formula there in LaTeX-Code. (Jug)
