best emacs command for search-navigating your command-line

i've noticed navigation of own command-line rather clunky, e.g. command like:

 % somecommand.pl --foo 123 --bar 456 --foobar 789

my cursor begins on "9" , want move after "3". rather dumb combination of jumping beginning of words, end of word.

i'd rather "jump-to-this-specific-character" command. emacs have command? there shorter key sequence me want?

the problem doing ctrl-s incremental search is:

i have explicitly hit "esc" out of search mode
if overshoot search, end searching older commands in command-line history, don't want. want jump around in current command.

am over-thinking this?

the elisp code fragment

 (setq saved-point (point)) (begining-of-line) (and (searchforward string (line-end-position) t)      (goto-char saved-point))

will first occurence of string on current line, , leave cursor @ current point if there isn't such occurence.

how want incorporate such code practice? bind key prefix waits next key, , looks string containing character.
