Hi,

Is there a way to search all Header Files in XCode?

For example, I look at this below and don't really understand, and I
want to search for the Definition of CGDirectDisplayID.  What is
CGDirectDisplayID?  How you can you subtract 1 from it.  How would I
find it's definition to further investigate this?


#define    INVALID_DISPLAY        (CGDirectDisplayID)-1
CGDirectDisplayID            gCGDisplayID = INVALID_DISPLAY;

thanks,
joey
