You use Emacs, you like [[https://gitorious.org/evil/pages/Home][evil-mode]], but when you type =:tabnew= nothing happens. Install this.
** Installation
If you're hooked up to [[http://melpa.milkbox.net/][MELPA]]:
M-x package-refresh-contents M-x package-install RET evil-tabs
(Alternatively just grab the single =evil-tabs.el= file and install that in your preferred way.)
Then add =(global-evil-tabs-mode t)= to your =.emacs= file, and eval it.
