    Edit: Thanks to help from @mathiasbynens, @subzey and @beaufortfrancois we are now down to 115 bytes from my original 136.
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 original 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.oninput=function(){l[k]=q.innerHTML;}})(document);

A demo version of this is available on JSBin.
The optimized version (115 bytes):
!function(l){with(document.body)contentEditable=!0,innerHTML=[l.c],oninput=function(){l.c=innerHTML}}(localStorage)

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.oninput=function(){localStorage[k]=q.innerHTML;}})(document);
