!:n
The nth word of the previous line — the command is word zero.
The previous line is sliced into words, numbered from zero. !:1 is the first argument, !:2 the second, and so on.
It's the precision piece of the box: when the argument you want sits in the middle of the line, it comes out alone, without its neighbors.
