Press alt and dot (full stop) to insert last word from the previous command line:

    $ cat file
    $ grep stuff alt-.

Alternatively, make use off the READNULLCMD mechanism in Zsh:

    $ < file

translates to

    $ ${READNULLCMD:-more} < file

Thus you can

    $ < file

then UP (or ctrl-p which I find more ergonomic) and continue with "grep stuff":

    $ < file grep stuff

(Redirections can be anywhere in the command.)
