Show hide query results pane shortcut is changed in SQL Server 2012 version.

If the settings are imported from SQL Server 2008 settings, then it remain same CTRL +R. Otherwise CTRL+SHIFT+ALT+R will show hide the query result pane. (Show and hide the query result pane, not only to show)

But when I look into the reference link, it says

Show or hide the query results pane -> CTRL+R

Show the query results pane -> CTRL+SHIFT+ALT+R

What it means?
