Comment 5 for bug 891620

Owais: the escaping strategy has not been considered, however releasing over the BFB or the currently focused application simply does a "quite safe escape". Maybe making the Esc key to work as on Alt+Tab could be a nice feature.

About the circular thing, I'm waiting for design input, while about starting from the current app or not is a design decision (you should be always able to know what will happen after a fixed number of key press).
