Yes, that's more intuitive (even though not reachable with hands at the
home row, no biggie  :)  ).  It'd have to support both cases though, of
when a filter is already present, and when it isn't.  With an existing
filter, I guess the whole list contents could change with each press of the
arrow, including possibly an empty list for a particular column.
[Backspace] in list-filtering is supposed to invoke, "return to the
selection prior to starting the current filtering", so that'd have to
include the column selection, if any, too..
