I'm using the latest gnome-shell on Ubuntu 13.10
and really like it. One question though. On 13.4 I used to get
a transparent panel at the bottom showing me what applications
are running, usually when I hit the hot corner (I think!) .
Since upgrading I've seen it a couple of times but can not get
it regularly, and have no idea how I got it visible. Can anyone
help ?
<super>+M or slide the mouse pointer into the bottom edge of
screen with a bit of speed.
