[super]+M shortcut

[Tomas M <tmezzadra gmail com>]

[super]+M brings the message tray. great. since using the mouse is useless as it is now (delay is annoying).

Now to hide the message tray, i would intuitively hit [super]+M again, but instead i have to hit ESC.

is this the desired behaviour? can i change this with a keyboard shortcut? i did not find the option.

thanks i.a.

Regards,

Tomas
