     As someone who is doing serious native-mode (Application Kit)
NeXT programming and interested in exchanging technical information,
I'm more than a little bit distressed by the poor signal/noise ratio
on this list.  Some of the worst offenders appear to be individuals
who have never even seen a NeXT.

     Some flames are worthwhile.  The source code issue, comments
about various design issues [e.g. power button, making the mouse right
button useful, etc.] are of concern to all of us.  The attributes of
toy computers such as the Amiga or Atari ST (or even Macintosh) are
not.  Nor, really, are the comments about whether or not a NeXT is
worth buying.  That is a matter between you, your moneybags, and NeXT.
If you love your Amiga I am very happy for you.

     Now, to put some signal into this noisy message: I am *still*
trying to figure out how in an NX_LISTMODE matrix how to
programmatically get the effect of COMMAND/LEFT-MOUSE on a matrix item
(that is, *add* it to the selected items instead of making it the only
selected item).  Merely calling highlightCellAt::lit: visually does
the right thing, but leads to bizarre effects when you try selection
modification via the mouse.

     More specifically, what I have is a matrix of ButtonCells inside
of a scrolling view.  I can have any number of those cells selected.
I want to do so by program control (e.g. call a subroutine that will
'select item #23') or by the mouse (via LEFT-MOUSE, SHIFT/LEFT-MOUSE,
or COMMAND/LEFT-MOUSE...damn it, give me the goddamn right button!!).
I want LEFT-MOUSE on a single item to clear any previous selection
(which it does normally, but not if you highlighted various items by
program control).

     How can I do this?  Or, what else do I do besides highlighting to
make sure the list mode matrix knows that I've done this to some other cells?
