Small update - I did find setSelectionFrom:to:anchor:highlight which
seems not to deselect the previous selection, but all this still feels
like a big nasty hack... so I'm still asking... is there a better way
to do what I want to do?

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
