Basic 3-seconds question

[Shogun]

Haven't found this on any of the threads, probably cuz it's so basic. (As will become obvious, I'm not a ref.)

True/False: As long as a player has at least part of one foot on the line (the rest of him stays in the key), there's no violation, forever.

True/False: The count starts over if the player is in the key and puts part of one foot on the line (and then goes back to camping).

Thx.
