Using buttons in Prompt for User Input for things other than OK and Cancel

As is, if I hit the Escape key after bringing up this prompt, it triggers the "Top" button instead of the Cancel button and thus inputs Top into the variable. How do I ensure that the hitting the Escape key properly accesses the Cancel button?

Correct. The first button (which is displayed right-most) is the default button (pressing Return will trigger it), and the second button is the cancel button (pressing Escape will trigger it).

I read about it online and tried setting the Cancel button to exactly "/.Cancel" but that just put those characters into the GUI.

Add "/." to the name. I don't know where you are seeing "/.Cancel", the example shows "Help/H"

That said, the right most button should be the default button. If you really want Cancel, Top and Bottom, then you should have buttons:

Top/ (default) or Top/T (T)
Bottom/B (B)
Cancel/. (Escape or Command-.)

Note that if the dialog has text fields, then it would be Command-T and Command-B, but if the dialog has no text fields, it is just the letters by themselves.

It looks like a bug to me. We'll have to wait for Peter to be sure.

It's not a bug, the default keys are based on position not whether the Cancel option is on.

And the right0-most button should never be Cancel on a Mac, it should always be the default button.
