I am  a traditionalist  and prefer F2  to stay were  it is.   Maybe it
gravitational  lenses  back  to  a time  when  Liberal  Arts  students
programmed  and   wrote  marginalia  or  translations   between  human
languages.  Academic papers are printed in two-column.

2C-mode needs a tutorial style introduction for newbs.
