You should look in the Coco3 service manual on page 40 to see how the keyboard is laid out. You 
should look at the Spectral Associates "Color Basic Unravelled", page B 79, where there is a 
disassembly of "Read the Keyboard" at $A238.
You could also check the contents of $152-$159 to see what if any data is placed there after an 
arrow is pressed.
