Inadvertant Contact

And another unrelated question/concern as a new official is how to remember to put my open hand up on the type of out of bounds when a player either steps on the line or bounces the ball on the line and keeps playing. My instinct is to run towards where the infraction occurred pointing at the ground. I always point the direction and verbalize the color, instead of putting up my open hand as I would when a ball is just passed or shot out of bounds.
