revset query builder: keyboard navigation should have effect
Created originally on Bitbucket by anpol (Andrei Polushin)
Revision Set Query Dialog has 4 lists at top.
When I use mouse to click on a list item, that item is selected, and non-list controls are changed as follows:
the query editor's selection is replaced with the item text,
the status tip is changed to describe the list item in focus.
When I use keyboard Up/Down arrows or Home/End keys, the list item is selected, but the non-list controls are not affected in any way.
Expected behavior: keyboard navigation should have the same effect as the mouse navigation. When I put the list item in focus, other controls should change consistently.
