<li>Emacs began at the Artificial Intelligence Laboratory at MIT. Beginning in 1972,
staff hacker CarlMikkelsen added display-editing capability to TECO, the text editor
on the AI Labs IncompatibleTimeSharingSystem (ITS) “Display-editing” meant that the
screen display was updated as the user entered new commands; compare the behavior of
"ed". In 1974, Richard Stallman added macro features to the TECO editor.</li>
<li>In 1976, Stallman wrote the first Emacs (“Editor MACroS”), which organized these
macros into a single command set and added facilities for SelfDocumentation and to be
extensible. TecoEmacs soon became the standard editor on ITS.</li>

<h3 id="org82bb85b"><span class="section-number-3">2.3</span> What is ELisp?</h3>
<div class="outline-text-3" id="text-2-3">
<p>
Elisp is a dialect of Lisp specifically written for Emacs. It makes it super
easy to configure Emacs if you know just a little bit of Lisp. Lovers of Erik's
scheme talk will feel right at home with ELisp! (everything is defined in terms
of elisp functions, even moving the cursor and entering text)
</p>
<p>
In fact, let's take a look at an example.
Here I will split this window into three sections:
</p>
<div class="org-src-container">
<pre class="src src-emacs-lisp">(split-window-right)
(split-window-below)
</pre>
</div>
<p>
To cycle through these windows, I press "C-x C-o".
As you can see, I cycle through in the order they were created.
</p>
<ul class="org-ul">
<li>However, what if I wanted to go back a window?
<ul class="org-ul">
<li><p>
Emacs doesn't provide a keybinding for this by default, so let's make
it in Elisp ourselves!
</p>
<div class="org-src-container">
<pre class="src src-emacs-lisp">(defun go-back-window ()
(interactive)
(other-window -1))
</pre>
</div></li>
<li><p>
Let's add a key binding for this!
</p>
<div class="org-src-container">
<pre class="src src-emacs-lisp">(global-set-key (kbd "C-c u") 'go-back-window)

Org mode is notorious for taking over programmer's lives. It's motto is
even "your life, in plain text". You can create calendars, make Latex
documents, make websites and blog posts with your own CSS, export to
Open Office formats, really anything you're creative enough to figure
out.
