ElScreen

This is a fork of ElScreen updated for Emacs 24 and package.el. ElScreen is an Emacs utility with which you can have multiple screens (window-configuration) on your GNU Emacs as well as GNU screen on terminal.

If you use emacs-lisp applications which have many windows (like Gnus, irchat, Wanderlust, Mew...), ElScreen makes it easy to switch to a different screen, with its configuration unchanged. You can also create and kill screen, jump to them, rename the screen, and so on.

This version of ElScreen does not require any external dependencies.

Installation

The preferred way to install ElScreen is through MELPA and package.el. If you have Emacs 24, you should already have package.el. To enable MELPA, add something like the following in your .emacs.d file:

(add-to-list 'package-archives
     '("melpa" . "http://melpa.milkbox.net/packages/") t)

Once you have installed ElScreen, you can activate it like so:

(elscreen-start)
