How do you set 'Space Bar' as key equiv on an NSButton?

I've got a very small app that I'm just using to test stuff, and I'm seeing
something I don't fully understand.

The app is very, very simple: One window, containing a standard NSButton and
a standard label. When the button is clicked it sets the label to 'Hi
there'.

It works fine when I use the mouse to click the button.

However, I'd like it to also happen with I press the space bar. In Interface
Builder I've highlighted the button, clicked on 'Key Equiv' and hit the
space bar. A tiny square 'u' appears. I save the IB data, run the app
and...space doesn't click the button.

When I set it for something else (Enter, the letter 'g' etc) it works as
expected, just not with space.

What am I missing? It's not overly important, just one of those wee things
that puzzles me.

This is on the latest XCode and IB.

Thanks.

Never mind, got it: defined another IBOutlet to the button itself, then
called 'setKeyEquivalent:@" "'. For some reason doing it that way works.
