A shortcut would be great, but it would also be nice if there was a button (beside the options drop down list) that would do the same. Easier to point out to new users and people who don't use shortcuts frequently. One or both variations are needed - when you have 10 option sets with 3-10 options in each the list gets very long, and it's frustrating and time consuming when you have to frequently bounce back to the main model.
