Neither am I.  I don't even know what program you are using.

But I well remember  the sheer panic  in the faces of  plenty of newbies
learning how to use Windows Word.  They wanted to type "Ah" (without the
double quotes),  mistook the  Control key for the  Shift key when typing
the "A" (which marked all the text already typed), then typed "h" (which
replaced the marked text  with a single "h"  in the upper left corner of
the screen), and then yelped.

Not at all sure whether or not that's what happened to you.

Sincerely,
  Rainer
