A little patience on your part wouldn't go astray. Aside from the fact it was after midnight, my time, when you posted and I have a life to live outside of waiting for new posts on the dozen or so forums I support, it's quite possible those 'views' represent nothing more than web-bot accesses.

As for your problem, your description suggests you've re-assigned the Fn–Right Arrow shortcut or the Command–Down Arrow shortcut to the D. As I don't use a Mac and this isn't a specialist Mac forum, there may not be anyone here with detailed knowledge about such tings. That said, see:
