"~/.emacs" file with the following contents:
(global-font-lock-mode 1)
;;10pt Monaco
(set-default-font "-apple-monaco-medium-r-normal--10-120-75-75-m-120-mac-roman")
(setq column-number-mode t)
(setq standard-indent 2)
(setq scroll-step 1)
(setq idlwave-shell-explicit-file-name "/usr/local/rsi/idl/bin/idl")
(setq idlwave-shell-automatic-start t)
(global-set-key [wheel-up]'(lambda ()(interactive)(scroll-down 2)))
(global-set-key [wheel-down]'(lambda ()(interactive)(scroll-up 2)))
(setq mouse-wheel-scroll-amount '(2.1))
