 Type along with the morse, but don't see what you're typing (unless you make a mistake)\&. You are allowed to get ahead as much as you want\&. If you get too far behind it will stop and resync with you\&. You can force it to resync at the next word end by hitting control\-H\&. Hit ESC to see how you are doing, control\-D to end\&. (The rightmost space in the printout marks where the average is\&. Farther left spaces separate off blocks of letters that are about twice as probable as the average to occur, three times, etc\&.)
