Mechanics for foul on successful 3-point try

[Lotto]

The following came up in my last game and I wasn't 100% sure what the proper mechanics were, so I thought I'd pose it as a question here.

A1 is fouled by B1 during a 3-point attempt. The ball goes in. The basket counts and A1 will be shooting 1 FT, but what signals do we give when? Choose and order from the following list---both for how one should signal at the spot, and reporting to the table.

Three-point field goal attempt (three fingers)
Three-point field goal successful ("touchdown")
Stop clock for foul (fist)
Goal counts (motion of hand in downward direction)
Type of foul (push or "hack")
