GAPI and virtual key code for 4th button

Hi all,
I have a Jornada 568 that has the standard 4 buttons on the bottom of the device plus the arrow keypad. The GAPI routine GXGetDefaultKeys only returns data for vkA, vkB and vkC. Is there a standard hardware code for "vkD" or that fourth button? On my device its virtual key is 213. The others are 209, 210 and 211 and vkStart is 212.
Are these fairly standard? What are people doing to query that 4th button? I'm using GetAsyncKeyState but don't want to hardcode in 213 if it's incorrect.
Thanks for any info.
