Sorry my terminology is not as educated as those of others; I'm prone
to using the "wrong term" for what I mean to say.  The JButton looks
just like - as if - you are in the process of clicking the button with
your mouse.  Like if you press a form button on a webpage; the JButton
looks exactly like that; there is a thin black box around the JButton
text; the colorization appears as if selected as well as focused.  The
button looks like that even if I have

backButton.setFocusable(false);

However, the moment I use *BOTH* of these lines:

backButton.setFocusable(false);
backButton.setSelected(false);

The button looks like I have *NOT YET* clicked onto it as well as
focus being diverted away from that button.

I hope that makes more sense.
