- when only selecting a single item, ticking its checkbox or simply selecting it using a click or tab tap doesn't make a difference
- when multiple items are selected, starting a drag on a previously unselected item ticks the checkbox of this item and adds it to the set of already selected items - the drag includes all of these items.
- when multiple items are selected and you select an item by clicking or tapping on it, the preview only shows this itemthe details of the latter.
- when multiple items are selected and you open any item (selected or not), only that item is opened. The other items remain selected, though, as does the just opened item.
- when executing an operation, it is always executed on all currently selected items, whether they have been selected by ticking their checkbox or not.
