JFK SHAGS A SAD SLIM LASS (solution)

by C. Scott Ananian, Andrew Lin, and Philip Newman

This puzzle is completely contained in its title.

When you type the title on a keyboard, you ought to notice that almost all the letters are on the home row.

If you connect the letters typed with lines on a picture of a qwerty keyboard (ignoring spaces), you will draw an arrow:

              I
 A S D F G H J K L
              M

The arrow points to one particular key. Since the title was in all caps, you should hold down shift while pressing this key, producing a COLON.
