I noticed the any of the Paste Dialogs (Paste as HTML, Paste as Text, etc) on Mac still saids "Use CTRL+V on your keyboard to paste the text".  I did a bit of searching in the CuteSoft folder and did find the "Use APPLE +V on your keyboard to paste the text" in the xml files so I guess somehow it's not switching over?  I tried this on your DEMO site and it still saids CTRL + V.

 

Thanks
