KTE::View signals
textInserted (KTextEditor::View *view, const KTextEditor::Cursor &position,
  const QString &text);

cursorPositionChanged (KTextEditor::View *view,
  const KTextEditor::Cursor &newPosition)

KTE::Document signals:
textChanged (KTextEditor::Document *document);
textInserted (KTextEditor::Document *document,
  const KTextEditor::Range &range);
textRemoved (KTextEditor::Document *document,
  const KTextEditor::Range &range);
textChanged (KTextEditor::Document *document,
  const KTextEditor::Range &oldRange, const KTextEditor::Range &newRange);

There is no way afaik to get a TAB keypress but an event filter...
