Hi,

As far as I understand it, \!^ expands to the first argument of the 
command, like \!:1 (Actually, I just learned it should be \!:^, but in 
case of ^, $, *, - or % as argument selector, the ':' can be omitted).
However, I didn't know that \!:<n> is possible, otherwise I would have 
used that, \!^ was just the first solution I found (as I said, my 
experience with shell programming is very basic...).
