Because whoever wrote the keyboard navigation for search, decided to auto select the first entry and require using up/down to navigate the result list, keyboard users can never select Show More.
Sure you can tab your focus to show more, but pressing enter, causes the first search result to be loaded due to the up/down key bindings.
I’d like to rip out the up/down key bindings and allow tab to work, as it always does for keyboard users, it sets the focus of the link you want to open. That is how tab is intended to work for keyboard users, that is how it has always worked. Search results are breaking that and it is frustrating to say the least
Anyone care, if I tackle this and make the search results more keyboard friendly? As I plan to attempt it this weekend. Which will allow the Site Map Menu, User Profile Menu and Search to all work the same.
