Reuse command

I'm wondering if there is a simple way to re-use commands when using the terminal. Consider the following:

$ mkdir /mnt/photo/2008
$ mv *.jpg /mnt/photo/2008

Doing this I used /mnt/photo/2008 twice, is there some simple way I can re-use what I issued to mkdir, in this case /mnt/photo/2008. The shell is zsh, I know I can assign a variable but this does not save time when just doing that ...

Re: Reuse command

Use the up arrow to get the previous command, C-a to move to the beginning of the line, delete the first word and type the new command?

Oh, there's also some fancy things you can do with the history command and '!' keyword. I never learned those though.

The fancy stuff is what I want. I've tried to google, but I guess I use the wrong search words

Also Alt+. (dot) by default to fill it in in the prompt.

Re: Reuse command

$ mkdir /mnt/photo/2008
$ mv *.jpg !$

That's the right answer, but it got ignored, why?

Re: Reuse command

another trick that i use quite frequently is the ^ for substitution.  for instance:

myprompt > ls /etc/foobar.conf
myprompt > ^ls^nano

it's also really handy for correctly spelling mistakes in the previous command.  i think it respects normal bash quoting, so ^mkdir^'mv *.jpg' might work for you.
