Slide
A slide is different from a sweep because a sweep does not require your to build momentum by lifting your free leg and standing on the ball of your other foot. Also, a sweep is a circular clockwise or counter-clockwise motion, whereas a slide is unidirectional.
There are at least 10 general ways in which you can slide, with 5 ways for each foot.
Starting with both feet together facing at 12 o-clock, you can jump on the ball of your right foot without becoming airborne so you can gain momentum as your left foot slides to 12, 10:30, 9, 7:30 or 6 o-clock.
Likewise, starting with both feet together facing at 12 o-clock, you can jump on the ball of your left foot without becoming airborne so you can gain momentum as your left foot slides to 12, 1:30, 3, 4:30 or 6 o-clock.
For styling, your body and foot can be perpendicular to the direction of travel. For example, if you step toward 12 with your left foot, then your body and left foot can point at 3 o’clock. If step toward 12 with your right foot, then your right foot and body can point at 9 o’clock. As another example, your body and feet can point at 10:30 if you are traveling to either 7:30 or 1:30 o’clock because 10:30 is perpendicular to the direction of travel.
