Key Values
Key values for each plane are stored in the registry. All units shi pwi th a
default key mapping already loaded in the registry. Applications that wish
to change the default mapping need to read the appropriate key from the
registry intoan array of Words, modify the values required and then write
the updated values back into the registry. The registr y access can be done
with standard Microsoft API calls, such as RegOpenKeyEx(),
RegQueryValueEx(), and RegSetValueEx().
