Selecting tasks

After you've created a task, you can select it by clicking on it. Selecting a task enables you to copy, cut, or delete it.  Once a task is selected, you can use the arrow keys to select the next or previous task.  You can also use the delete key to delete it.

Multiple tasks can be selected though one of three ways:

Holding down the Alternate key while clicking on an item selects all the items between the first-selected item and the clicked-on item.
Holding down the Shift key while clicking on an item adds that item to the selection if it was not selected and removes that item from the selection if it was already selected.
Holding down the Command key before dragging will cause the items dragged over to be selected.  If you press the Command key after you begin dragging, it will have no effect, and the item will be dragged instead of a selection being made. Similarly, alt-dragging and shift-dragging start a drag, not a selection.
