Dynamic triggers

The action of dragging one or more icons and dropping them onto another icon is called a ``dynamic'' trigger, to contrast it with a static trigger. This is also sometimes referred to as a ``drag'' trigger.

The dynamic triggers are pre-defined as follows:

drop

drop one or more icons on an icon or window background

alt_drop

drop one or more icons on an icon or window background with mouse button 2

d*

matches any drag trigger
