Newbie Puzzled by Deleting Card

There are a few things that are not immediately obvious about Rev. These 
sorts of things make certain operations several steps more difficult 
than you might expect, at first. That's the essence of Rev's learning 
curve. While the information is usually in the documentation somewhere, 
sometimes you have dig for it without necessarily knowing exactly what 
you're seeking. As more examples, tutorials and cookbook material become 
available it will become easier to more quickly understand some of Rev's 
design constraints and features and how to accomplish "simple" things.

For example, to make a typical HyperCard-like stack where multiple cards 
share the same elements, you must _group_ objects that you want to 
appear on each card, such as buttons and fields, and then enable 
Background Behaviour for the group.

Once you do that, a delete button that's a member of the background 
group can work to delete the current card as you would expect.
