NAV 2013 Spell Checker for List Pages

hi,

I have just implemented this spell checker on NAV2013: http://mibuso.com/blogs/ara3n/2009/11/2 ... amics-nav/

But unfortunately I can't get it to work on the Sales Comments Sheet because it's a List Page, it worked perfectly when I changed the page to a Card. Would you know how I can modify it to work also on List Pages?

Thanks in advance!!
