command+h hides a window. Is there a keyboard shortcut to show it again? I always have mail open but the window hidden. It shows up in command+tab but it only makes mail show on the menu bar - not too useful. Short of a way of making command+tab show an open application's window is there a keyboard shortcut that would allow me to command+tab to an app and then show the window? i.e. command+tab then ???+??? to show the window. Any help would be appreciated.
