Excel Shortcut Question - Excuse me if this is Noobish

Is there a shortcut that will reveal all grouped cells into there expanded form (the action when you hit the small number two in the top left corner)? I tried to google this but not sure what this is exactly called. Any help would be appreciated. Thanks.

Alt D+G+S ?

Thanks, that actually works when you are in the row or column that is grouped. But I guess if you want you can select all and then Alt DGS. That shows all of them. That works.
