In explorer panel, using keyboard to type first letter of file name causes the first file or folder starting with that letter to be selected. This is good. However, typing the same letter again should cause the next matching file/folder name to be selected. Instead, just the first matching file/folder remains selected.
In a long list of file names, I should be able to type S S S S and have the forth file starting with "s" selected. This is how Microsoft Explorer works.
