(function (d) { // Alias for current document
l = localStorage, // Alias for localStorage, used for storing text content
k = 'c', // namespace for storage
q = d.body; // Alias for document body
q.contentEditable = true; // Switch on contentEditable
q.innerHTML = l[k] || ''; // Set content to localStorage value or empty string
q.onkeyup = function () { // On keyUp, update localStorage value to textContent of your contentEditable area
l[k] = q.innerHTML;
}
})(document);
(function(d){l=localStorage,k='c',q=d.body;q.contentEditable=true;q.innerHTML=l[k]||'';q.onkeyup=function(){l[k]=q.innerHTML;}})(document);

I use this as a JavaScript snippet or bookmarklet in Chrome to turn the current blank tab into an offline text-editor which stores what I write in localStorage. The < 140 character version can be run via console.

The simplest version that you can add as a bookmarklet:

(function(d){l=localStorage,k='c',q=d.body;q.contentEditable=true;q.innerHTML=l[k]||'';q.onkeyup=function(){l[k]=q.innerHTML;}})(document);

A demo version of this is available on JSBin.

And this time actually including var:

javascript:(function(d){var l=localStorage,k='c',q=d.body;q.contentEditable=true;q.innerHTML=l[k]||'';q.onkeyup=function(){l[k]=q.innerHTML;}})(document);

Or using oninput, which also works fine and should catch paste etc:

javascript: (function(d){l=localStorage,k='c',q=d.body;q.contentEditable=true;q.innerHTML=l[k]||'';q.oninput=function(){l[k]=q.innerHTML;}})(document);

Pretty version

Prettier version of the implementation using document.write (hah) to write over any existing tab content, gives you some styling too:

javascript:(function(d){d.write('<body contenteditable style="font: 2rem/1.5 monospace;max-width:60rem;margin:0 auto;padding:4rem;">');var k = 'c'; var q = d.querySelector('body');q.innerHTML=localStorage[k];q.onkeyup=function(){localStorage[k]=q.innerHTML;}})(document);
