Heads up, shortcut key to access messaging/sound indicator menus.

[Hammer Attila]

Hy Luca,

This shortcut (Super+s) is working if the indicator applet and indicator 
applet session applet is added the top or bottom panel. But, if the 
indicator session applet is added any panel, this applet remove the 
logout user and shutdown menus from system menu.
I think if an accessible install happening with any blindness profile, 
the indicator applet session is not default added a panel.
For example, if I added this applet my bottom panel and press Super+s 
key combination, the guest user choose is awailable. If this applet is 
not enabled, have another way to choose the guest session? Guest session 
user have a default password, or nothing defined and enough to choose 
for example switch user, and the accessible login dialog enough to 
choose other... item and type guest username and not type any password? 
Prewious time I newer tryed the guest session, sorry the possible 
trivial question.
