Question on the 3 second key rule
Makes perfect sense. That's why players cut across from one side to the other. Otherwise you could simply camp out behind the baseline waiting for the right moment to step in.

Yeah, I've also heard the 'illegal to go out of bounds to gain an advantage' rule, but that was back when they had the trapezoid lanes, so you couldn't have the key extending indefinitely without serious amounts of guesswork.
The baseline is explicitly not part of the restricted area, though, so I can't imagine the out-of-bounds area is.
Neither the rulebook nor the official interpretations deal with this case, though.

I can be corrected but I seem to remember that A player i also supposed to ask permission to leave the floor, AND , more importantly, is not able to go outside the playing area, and doing so in order to gain an advantage that is outside the rules can also be argued is grounds for a teck.
At least the fascist old school referee that I had to put up with in the 1980 used to try both those calls when he had the proverbials with a player.

Rule doesn't apply if you step outside the court. You have to be inbounds and step out of the key with both feet for the count to be reset.
