George is right.
You actually have to put the "em" in. I have tried just the _ but it shows up. The "em" is made by holding down "alt" the pressing 0160. The will put your "em" in and spread the words apart and also anything that is connected with the "em" will be one space bar tap, so your 7 6 5 4 3 2 1 will all be one tap.
