Browser as notepad

From time to time I need to note something down, from a snippet of code to some lorem ipsum.

Of course I can open a text editor and paste the text there but is it worth it to keep another window around when I have already a browser open in one of my screens?

Why not use the browser as notepad?

Just copy this code into you url bar and press :

data:text/html, <html contenteditable>

And paste the content or start writing something in the body ;).
