changing start menu search default selection search th

For some reason after Beta 2 in build 5456, the default selection of any search generated list of files is "Search the computer" from the start menu search feature.
Since we're searching in the start menu, shouldn't we already know that it will only display the indexed files? I find it a little annoying when accessing documents to have to type the keyword plus a few arrows up and an enter.
Is there any way to change the default selection back to what it was in Beta 2, where the first document was selected instead?
