Hi Rufus-
No offense to you or anyone else, but is there a specific reason why you
need to do that? If so, OK, I don't mean to interfere. I understand that
certain gov't. agencies & organizations insist that this technique be
followed even though it is antiquated and unnecessary in the documents we
produce today using scalable fonts with proportional spacing.
The 2-space technique was adopted to prevent the appearance of 'crowding'
sentences when typed on our trusty old Royals & Underwoods. Typewriters are
monospaced devices which make no distinction between '. W' and '. I', whereas
the software & fonts we use on the computer adjust the spacing to what it
should be based on standards used by the typesetting industry. Using just the
one space will give the same spacing in your documents as you would find in
professionally printed magazines, newspapers, journals, books, etc.
Quite frankly, I originally misread your post and almost offered a totally
differeent response because the question I am far more frequently asked is
"How do I *remove* the two spaces and replace them with one?".
Hope this is useful & taken in the helpful manner intended. It's a shame to
spend time on something that need not (and arguably, should not) be done |:>)
