I assume your editor is a TextArea object, so how do we get the selectionStart and selectionEnd properties?

 

Source content of a web page with CE Editor on it shows:

 

 <!-- CuteEditor Editor1 Begin -->

<textarea name="Editor1" id="Editor1" rows="14" cols="50" class="CuteEditorTextArea" style="DISPLAY: none; WIDTH: 100%; HEIGHT: 100%">#1html#2
