Better than that for me is "Alt+.", much easier to type. It can be also combined with number like "Alt+2+." will insert second argument. Similarly "Alt+0+." will insert last command. http://linuxcommando.blogspot.in/2009/05/more-on-inserting-a...
Yes, I know about iTerm. I don’t want it.
$ echo a b c d
a b c d
$ echo # pressing <Alt+<2>+.> here inserts 'c', not 'b'.
