I kind of think that if you have to document something like this,
Specific suggestions I have include:
1. Lift the screen on press of shift or control, the traditional keys for
clearing a screensaver (I think there's a bugzilla for this)
2. If someone is moving the mouse around for a while and hasn't figured out
what those arrows mean, maybe display some text? Or something that looks
like a clickable button?
I am running gnome-shell-3.9.4 on a mostly F19 system, and what happens is
that when you start typing the curtain is automatically lifted. The same
happens if you press enter.
Life is like bein' on a mule team. Unless you're the lead mule, all
the scenery looks about the same.
