What I really love about emacs is that it is so easy to move keys around and to assign function to keys. For example, I find this really useful on my MacBook Air keyboard: ;; Map option-up/down do page-up/down (global-set-key (kbd "ESC <up>") 'scroll-down) (global-set-key (kbd "ESC <down>") 'scroll-up) Now option up/down do paging. Win. (Probably already default in Aquamacs, but I prefer to use the 'real' Emacs.app)
