"alt + arrow key" shortcut in Ableton 9

[JunL]

Hello.

I have a question about the shortcut "art + arrow key".

This shortcut functioned as moving from certain windows to another.
(for example from browser to detail view or from session(arrangement) view to detail view)

This shortcut was pretty convenient to use so I usually used it.
But I noticed that this shortcut doesn't exist in Ableton 9.
So I searched the manual to find but couldn't find.

Is this shortcut removed? or changed to other key?
(if it is removed, I firmly request them to rescover this shortcut.)

If you have m4l, it's very easy to patch.
