Sorry Catdad , neither Joe or I have the Kensington so we're not familiar with the software. Hopefully someone who's set up a Kensington will read this post and help you out. All we can do is tell you how we did ours and hope that your software is similar, but I guess it's not. Having the leans on the side mouse buttons is much easier to use than the keys , at least it is for me. Good luck.
