Maybe it's more a case of folks not understanding what you're looking for in the way of a reply.
One hundred ninety words into your post, you ask the question What is AccessPad Pro®™? Three hundred seventy-nine words later, you answer "The AccessPad Pro®™ is a computer peripheral..."
This might qualify as case of "burying the lede." Though the rule never to do so arose originally as a principle of good journalism, it certainly applies to adverstising as well—if your audience still doesn't know what product they're being sold a couple hundred words into your ad, they're unlikely to wade through a couple hundred more to find out.
This is the right place to have posted; isn't it possible that the concept just wasn't of enough interest to anyone who read it to generate a response?
FWIW, I followed along just fine, but I don't think most computer users are looking for more key combo permutations; we already have hundreds. That's why there's such enthusiasm for touchscreens and touchpads: they allow for more direct interaction between the user and the objects on the screen, eliminating the "abstraction layer" of keyboard shortcuts altogether. Just my two cents' worth.
