Hi Jeff --

In my particular case, for the horizontal spacing in response to an
ampersand, the type box moves rapidly over to the right, just like hitting
the tab function on a typewriter.  The TTY does not function (in the time
domain) like the selector magnets received 14 space chars.  So far it's
always been 14 characters, but I haven't done a lot of testing with that to
confirm.  I'll try that later today.  I do know that the right side cable
wheel on the front of the typing unit has some flanges that stick out on
the front of it about 1/4 inch, like it might be for tab stops, but I don't
see an actuator that would engage or stop based on the position of those
flanges.  I should probably open the housing cover and watch it as I send
it some ampersand characters, to see if I can understand the operation of
the tabbing function.

Paul, ad7i
