Wait maneuver - differences from 3rd Edition

GURPS Tactical Shooting implicitly (re?)introduced an option of taking a step and wait. Since it never explicitly did so, it didn't actually lay down rules for doing it...

There are hints which makes things more confusing.

1) In GURPS Frequently Asked Questions http://www.sjgames.com/gurps/faq/FAQ4-3.html, Wait is called Step and Wait maneuver.

2) If step is not allowed with wait, than what maneuver is a player to take in order to perform a "Slicing the Pie" (Tactical Shooting, p. 24)? It is a situation in which a man steps around a corner. Does he take a series of Step and Wait, or does he make a series of Step and Attack, giving up the attack each turn a valid target does not present itself?

3) In GURPS Lite, an update from 3rd to 4th edition, where the issue could have been addressed, there is no description of the Wait maneuver.
