quick question: how can I find out when the key F12 is pressed? (and of course do something when it is pressed?)

Assuming that this is AWT or Swing code, you'd add a KeyListener and trigger on KeyEvent.VK_F12 in one of its methods.

I don't think you can catch it in a command line application. Rather than the application catching it, the shell or command window will catch it, and not pass it to the app.
