When you search for something, and then use arrows up/down to highlight a search result - if you then use enter expecting to open the article you will instead go to the search page with whatever search term you've entered. Doesn't it make more sense that you go to the highlighted search result?

Might require to change the default so that the top search result is not auto-highlighted anymore (so that if no search results are highlighted and you click Enter, you go to search page as you do today).
