PW On-Screen Keyboard: Using the line above the keys?

Hi:

Regarding the Paperwhite 5.8.7 on-screen keyboard:
Is there a way to put values in the text line above the actual keys, that is used in Amazon's own Apps for word suggestions?

I am looking into ways to improve the usability of the gargoyle interactive fiction interpreter, and would like to place cursor-key commands there (like: cursor:left; cursor:right).
