listbox binding..what is the current selection?

[Rex Macey]

Thanks.  I have spent time with the docs, at least with the Python v3.3 and tkinter v8.5 (pdf).  I wish they had more examples. My approach is to browse the docs, try a program, fail, read the docs, try again.  When I can't figure it out, I post.  I appreciate the help.
