[Herts] quick magic key combo for bash

[local linux]

hi,

I came across this cool bash short-cut and had to share.
we all know about(i hope) CTRL+r to search history but try this

ls [tab] until you get a nice file path, press enter
then 
echo [ALT+.]
as if by magic it adds the file path you selected, best thing is you
can hit [ALT+.] continuously and get any parameter from past commands.
(sorry, not a very useful example).

Life saver.
