NSWindow: Custom title bar double-click action?

Hello,

When you double click on a window's title bar, the window is
miniaturized - if the window is miniaturizable. This is not the case
for HUD windows (or any panels). I have a "mini-HUD" the user can
enable via the application menu, and would like to set up a custom
title bar double-click action as a more convenient way to switch to
this mini-mode. Only problem is I cannot find any documentation on how
to do this. Any pointers?

Thanks.
F.
