The quick, brown fox jumps over the lazy dog.  Perhaps
you did not realize as you keyed the first sentence of this
paragraph that every character in the alphabet was stroked.
Obviously, this sentence serves as excellent warmup copy in
that it requires the stroking of all the alphabetic keys at
least once.  Through keying this sentence you can determine
if any of the letter keys are sticking or inoperative.  One
of the darker moments for a keyboarder is to begin a timing
only to discover that one of the keys is out of order.  You
might wish to memorize this sentence for your warmup drill.
     Now is the time for all good men to come to the aid of
their country.  Without doubt the preceding sentence is the
most practiced copy in our language.  Students with a quite
high skill level as well as the slow beginners always enjoy
keyboarding this copy to display their speed.  Just why has
this copy proved so popular with students?  The composer of
this famous line is unknown.  However, it is obvious to all
keyboarders that this copy is unusually easy.  This results
primarily from the copy being constructed of short words as
well as the words being composed of alternate hand strokes.
