Stumbled on this software today on a list of productivity tools -- Touch Cursor -- http://touchcursor.sourceforge.net/
This is free program for Windows PCs that re-maps some of the keys on your main QWERTY keyboard to function as arrow and other edit keys. The basic layout of their arrow keys I=up / J=left / K=down / L=right is the same as WayTools has picked. TouchCursor makes you hold down the space bar as the "special shift" key whereas WayTools uses two left hand home row keys.
This is fun to play with and really seems to validate for me how useful the "home row cursor" and edit keys on the WayTools are going to be.
The TouchCursor "key bindings" are editable so you could adjust them to better match more of the WayTools default layout if you wanted
Program works for me on my Win 8.1 PC
--> Website says my WayTools is in Manufacturing today. Looking forward to getting it!
