   Prior to Selectric there were plenty of electric typewriters with
   buttons for carriage return, line feed, or both.  The big button
   did both.

   But generally when we wanted to overtype an entire line uaually to
   add underscores) we pushed the lever hard enough to get the line 
   advance, or hit the wrong button, out of habit, the reached up and 
   rolled the line back.  Worked on LA36 and LA120, too, although we
   generally did it programmatically.

   But those knobs were missing from our VTs.  And overtyping with
   underscores left the text on the VT hard to read.
