So I did a lot more research on this today...
And it turns out, it looks like NSMatrix IS multi-select by default.
The problem comes from the same issue this guy ran into:
http://www.cocoabuilder.com/archive/message/cocoa/2003/12/15/89691
Specifically, he wanted to implement drag and drop support (so do I) -
which from the looks of that email, means I have to implement
mouseDown: and then manually call selectCellAtRow:column. The problem
then is that selectCellAtRow:column appears to *deselect* any
previously selected cells, which means basically that by implementing
his solution for drag and drop, it basically breaks multi-selection.
SO... I looked to see if I could find any methods that explicitly said
they do NOT deselect the previously selected cells, and I couldn't
find any. Can anyone suggest a good way to do this?
Again, what I want is an NSMatrix which allows multi-selection AND
drag-and-drop.

Hi,
I have a custom view which I have inherited from NSMatrix. Is there
an easy built-in way to make NSMatrix be allow multi-selection? Or
do I need to do some kind of hackery for it?
Thanks
