Keyboard and Android?

It sure would be nice if I could assign some keys to Android apps; either that or someone developed a Buzztime trivia app for Blackberry10. I tried such only to find that the folks over at Buzztime won't give me, an individual, access to the site needed for an app to work. I am left at present with an Android app that lacks a keyboard interface, and the Shortcuts menu in Settings doesn't seem to offer a solution, an option to get Buzztime to use the physical keys. Have I missed something?
