Since signals are simply a method of communication, some officials might use some sort of hand signal (maybe a fist into a palm for the fist violation, but be careful about trying to come up with a signal for ball up through the basket...). But it's usually better to stick with the approved signals, and simply use your voice to communicate the violations that do not have a signal associated with it.

The FT not contacting the rim is another example of a violation that doesn't have a signal. I've seen many officials use the "swirly"/reset the shot clock signal, but it is not an approved signal.
