IIRC, the arrows don't work with Android apps (as I don't use Alien-Dalvik I don't really know). Would it be too much to ask for you to install any 'arrow keyboard' (or 'with arrows') from OpenRepos and test whether the arrows work the way you want them to in Office Suite Pro for Android?
If they do, I can add all 4 arrows as an additional top row (which will make this keyboard totally useless in landscape but it wasn't very practical as such in the first place).
