#print
For symmetry, you can use

+

instead of either ".+1p" or an empty line (just a newline).
The only advantage that + has is that you can repeat it:

++

prints the second following line, and 

+++

the third.  The same is true of -.  If the current line is
line number 10, what line number is -- going to be?
(Hint:  you can find out by editing a file such as "pres",
saying "10p", and then saying "--",
and then saying ".=" - remember the "=" command?)
When you find out, type "answer N" where
N is the number.
