@nbs. Thanks for replying to help in a prompt and mature manner.
I have the most recent firmware for the X5. As mentioned, the keyboard when using chrome only moves left, up and down from t and never moves right. However, I found a work around. The keyboard is fully functional when using 'search history" so I was able to type in the address of the apk, then copy it and pasted in navigation bar and thus have downloaded the apk I need.
