Ctrl+Up/Down is supposed to move the focus up/down (not highlight). MediaMonkey seems to do this, but fail to show that the item is focused (dotted line around item). Confirmed with 3.2.4.

> is CTRL up supposed to have any standard behavior in such dialogs?

None I know of. But SHIFT => extend selection, and it would be useful if it did

> I would normally just use UP/Down arrows and would never have thought to use CTRL-UP in this case.

It takes a ruthless test mentality :)

... fail to move displayed criterion selection indicator.

In New Filter and View Options or Edit Filter and View Options

1 Add three Search Criteria
2 Press CTRL+UP ARROW

Expected: Criterion indicator moves to #2 especially since (unlabelled) DOWN button gets enabled
Observed: Criterion indicator remains on #3 but e.g. DELETE deletes #2!
