    Of all the Elisp I've written this grep is what I most miss when I use a coworker's environment.

    (defun my-grep ()
      "grep the whole directory for something defaults to term at cursor position"
      (interactive)
      (setq default (thing-at-point 'symbol))
      (setq needle (or (read-string (concat "grep for <" default "> ")) default))
      (setq needle (if (equal needle "") default needle))
      (grep (concat "egrep -s -i -n " needle " * /dev/null")))
    (global-set-key "\C-x." 'my-grep)
    (global-set-key [f8] 'next-error)
