Would someone please explain to me how a matrix accomplishes highlighting of a  
cell?

The documentation states that the contents of the cell is composited with  
NX_HIGHLIGHT, but I couldn't find a description of NX_HIGHLIGHT anywhere. It  
would seem to me that the AppKit handles the highlighting for you. However, in  
one of the NeXT MiniExamples, the background color of a cell is chosen in the  
code by checking the cFlags1.state and .highlighted bits. This suggests to me  
that it is up to the programmer to implement highlighting. Who's right?

On a related note, what happens to the cFlags1.state and cFlags1.highlighted  
flags of a cell during and after a mouseDown:?

Thanks in advance.
