Searchbar UI Eventshandler activation behavior problem

I was using the searchbar and found out that with listItem selected by mouse, whenever I clicked ENTER, it went to the page of the selecteditem. It is weird when pen tablet is used, because the mouse pointed somewhere without the user’s notice and each time when it is clicked a weird result returned. A better way to improve might be something like “up down left right + Enter”, and “mouseSelection + Click”.
