"Collapse all" groups in sidebar?

I believe that there used to be a key command that would close all open Groups in the sidebar.

In DTP 3, I can’t get this effect any more. Might it be added? or have I just not found it.


There is no longer such a command. The request is noted, but no promises.

There’s actually a command but it’s only available in the action/contextual menu of the sidebar if the clicked/selected group(s) can be collapsed/expanded. Multiple selected groups are also supported.
