Within the ''action'' string of the DroppableWidget, the <<.def modifier>> [[variable|Variables]] contains the modifier key(s) held during the drag-process.
The possible keys are ''ctrl'', ''shift'' or both ''ctrl'' and ''shift''
The variable contains a string that identifies the keys:
|Modifier Key |Variable Content |h
|ctrl |ctrl |
|shift |shift |
|ctrl+shift |ctrl-shift |
|no modifier (normal drag) |normal |

|class |Optional CSS classes to assign to the draggable element. The class `tc-droppable` is added automatically, and the class `tc-dragover` is applied while an item is being dragged over the droppable element |
|tag |Optional tag to override the default of a "div" element when the widget is rendered in block mode, or a "span" element when it is rendered in inline mode |
Within the action string, the [[actionTiddler Variable]] contains the title of the item being dropped.
Within the action string, there are two Variables generated by the DroppableWidget:
* The [[actionTiddler Variable]] contains the title of the item being dropped
* The [[modifier Variable]] contains the Modifier Key held while dragging (can be normal, ctrl, shift or ctrl-shift)
If multiple items are dropped then the actions are performed repeatedly, once for each dropped item.
