Navigation in palm

1. Creat a file .r and go to the Settings to map the extension r with
PalmRez
2. This file .r has the header that looks like :

#define hsNavFlags   defaultStartStateValue = 0x00000000, \
     objectFocusStartState  = 0x00000001, \
     appFocusStartState     = 0x00000002

#define hsNavObjectFlags none             = 0x0000, \
     skip             = 0x0001, \
     forceInteraction = 0x0002, \
     bigButton        = 0x8000

};
