This property holds whether the text is smoothly scaled or transformed.

When this method is called it additionally sets either the

to the specified position. This allows you to easily extend and contract the selected
text range.
For example, take this sequence of calls:
\code
cursorPosition = 5
moveCursorSelection(9)
moveCursorSelection(7)
\endcode
This moves the cursor to position 5, extend the selection end from 5 to 9
and then retract the selection end from 9 to 7, leaving the text from position 5 to 7
