Use either:
 1. QTextEdit::moveCursor(), but you need a for loop to go up/down for 
multiple lines. Example:
       editor = QtGui.QTextEdit()
       [...]
       for l in range(4):
            editor.moveCursor(QtGui.QTextCursor.Down, 
QtGui.QTextCursor.MoveAnchor)

 2. QTextEdit::textCursor() to get the cursor, then 
QTextCursor::movePosition() and then QTextEdit::setTextCursor() so that 
it takes effects. Example:
       editor = QtGui.QTextEdit()
       [...]
       cursor = editor.textCursor()
       cursor.movePosition(QtGui.QTextCursor.Down, 
QtGui.QTextCursor.MoveAnchor, 4)
       editor.setTextCursor(cursor)
