.PP 
drag and drop actions 

This is a bitmask of the available/preferred actions in a drag-and-drop operation\&.
.PP
In the compositor, the selected action is a result of matching the actions offered by the source and destination sides\&. 'action' events with a 'none' action will be sent to both source and destination if there is no match\&. All further checks will effectively happen on (source actions ∩ destination actions)\&.
.PP
In addition, compositors may also pick different actions in reaction to key modifiers being pressed\&. One common design that is used in major toolkits (and the behavior recommended for compositors) is:
.PP
.IP "\(bu" 2
If no modifiers are pressed, the first match (in bit order) will be used\&.
.IP "\(bu" 2
Pressing Shift selects 'move', if enabled in the mask\&.
.IP "\(bu" 2
Pressing Control selects 'copy', if enabled in the mask\&.
.PP
.PP
Behavior beyond that is considered implementation-dependent\&. Compositors may for example bind other modifiers (like Alt/Meta) or drags initiated with other buttons than BTN_LEFT to specific actions (e\&.g\&. 'ask')\&.
