Keybinding, lower window, focus next stacked window

Hi,

I'm trying to define a keybinding to lower a window and give focus to
the window that is just below it. For the moment I'm using ":MacroCmd
{Lower} {FocusUp}" but it does not do exactly what I want. If you know
how to achieve what I want, please let me know. Thank you.

Regards,
Pedro
