What does this do that having no Error catcher would not do? How is this
used? In testing, it simply takes you to the error; but wouldn't having no
"On Error" expresion do the same thing? Or, is this used when you want to
trap an error in a specific part of your code?

It turns off error trapping, so that the previous On Error Resume Next
or On Error GoTo Label no longer has an effect.
