There is some nice feature called auto-completition in emacs I use to less because the shortcut is real ugly.
At the moment I only work in emacs because I really like it.

Here is the code I put in my '~/.emacs' file so I can use this feature using "Escape"+"Enter"

(define-key global-map (read-kbd-macro "M-RET") 'hippie-expand)

it works great
