Adam,
Thanks for the reply, it is very helpful
Adam:
Please check the following article:
From that article, it seems that the methods illustrated will only work in Normal mode, not in HTML mode. Is there a way to similarly restrict the corresponding sections of code in the HTML view? I've seen it in other editors so I'm sure it's possible, just a matter of how. Maybe a javascript that runs on HTML tab click, which would search for anything outside EditableRegion tags and surround them with SPAN's set as unselectable and contenteditable=false. Is this realistic/possible?
