[Coco] How to type underscore in OS9 L1 under XRoar

[William Carlin]

I experimenting with Bill Pierce's pre-built OS9 L1 builds in XRoar and I
cannot figure out how to type an underscore.  Keyboard translation is
turned on.  Typing the underscore on the keyboard results in a period being
typed but that does not translate into an underscore when you want to copy
a file with an underscore in the file/path name.
