I don't get the idea.
I made a FREE PDF chat. And you are asking me to send you some info to update a PAID app? I believe that if you charge for your app, you should do researching for yourself or pay for it (I am not interested in doing that).
I don't mean you can't charge for your work, but it's unfair to advertise your app "as better" like this where someone is giving free stuff.
By the way, in FCPX you have a shortcut to open Command Editor and there, you have all the keyboard shortcuts with an excellent search function. For free. Included in FCPX.
