"Position within the file" should get focus when
pressing [Alt+P] in MS Windows (so that [Enter]
locates the source).
[Alt+P] appears to move the focus as expected but
[Enter] has no effect. There is a border around
the item if there is only one (no other cases
Only after pressing [Alt+P] 3 (three) times, the
focus becomes active with a solid blue background
and [Enter] actually works.
Search filesystems feature is implemented in utilities module.
Fixed in the trunk.
Verified in nb35beta and dev.
