REVISION SUMMARY
  While the idea seemed smart to reuse kparts plugins as handler inside
  the preview plugin, sadly this results in many clashes for keyboard
  shortcuts especially for central ones like "Copy".
  Which spoils the idea of a live preview while editing the text document,
  as one often runs in unusable shortcuts.
  
  Which is a problem in general with toolviews, which might have actions
  with shortcuts conflicting with those as registered by the currently used
  document view whose actions are integrated in the global app menu.
  KParts plugins in a toolview just escalate this more, given they have
  the usual view-centric actions with the respective common shortcuts.
  
  A solution might be to extend KXmlGui to somehow support such situations,
  and decide who owns the shortcut by looking at the focus.
