IS THERE AN EASY WAY TO CHANGE THE WHOLE FILE FROM UPPER CASE TO LOWER CASE OR
VICE VERSA? I DON'T WANT TO DO 26 SUBSTITUTIONS TO CHANGE CHARACTER BY
CHARACTER.

Hmm, yes, I believe there is!

Just a combinations of solutions I've seen.  To up-case a single
paragraph, you can type:

        {!}tr '[a-z]' '[A-Z]'

which will conveniently pipe the paragraph into the tr (translate) command.
To translate the entire file, set your cursor at the beginning and enter:

        !Gtr '[a-z]' '[A-Z]'

I've just learned of this method, deduced from the '{!}fmt' command
I've read in these postings.  This is an amazingly powerful feature!
If there's nearly anything at all you want to do from the editor that
it doesn't do now, just write it in C and there it is!  Altho, it's
extremely likely there's a utility, such as 'fmt', which already does
it.  In fact, I'm thinking of writing my own version of 'fmt' that will
take hyphens into account, plus auto-hyphening common suffixes and
prefixes.  So that you'd change, for example, "hyphening" to "hyphen-
ing", and back, as required.

Or does *that* already exist somewhere, too?
