Xcode's debugger has the 'pause' button in its toolbar, which is great.
Is there a way to do the same thing with a keypress? Like in the old
days pressing the programmer's switch to break into Macsbug.
It would be handy in situations like debugging someone else's code and
needing to break into the debugger without moving your app into the
background.
On Mac OS X it's not quite as straightforward as a hardware NMI. You don't want to interrupt the whole machine, you just want to send a signal to a particular process; how do you tell it which process? (I suppose you could write some global doohickey that sends a SIGINT to the frontmost process. But in general you should just either Command-Option-P (pause) when Xcode is frontmost, or build a "Debug" menu item into your app that calls Debugger() when you want it to.
