Ancestry.com have announced a change in the operation of their new search.
"After listening, researching and testing with members, we decided to make the hot key experience in new search the default method for refining searches.
This change will happen on Monday, November 9th, sometime during the day.
The information you enter into your original search will appear at the top left of the search results page. Clicking “Edit search” will bring up your search query allowing you to edit your search criteria."
I hope this doesn't mean the r for refine keystroke option goes away.
