Nice, i guess that pin can deliver enough power for the controller to work.
How does the controller handle CODE, GRAPH, SELECT and STOP keys. (how are they mapped.?)

This is neat! Is the source code available, and if so does the license permit modification? I looked in the repository but didn't know what file to look for

SELECT -> F6
STOP -> F7
GRAPH -> left ALT
CODE -> right ALT

yes, provided you do not use the internal pull ups, and the gpio in writing in open drain mode
