Heads up! This blog post hasn't been updated in over 2 years. CodePen is an ever changing place, so if this post references features, you're probably better off checking the docs. Get in touch with support if you have further questions.

There are now short URL’s for all the major views of a Pen.

Original Pen:

Short URLs:
Full Page: http://cdpn.io/esrtc
Editor: http://cdpn.io/e/esrtc
Details: http://cdpn.io/d/esrtc

And if you are PRO:
Live View: http://cdpn.io/v/esrtc
Collab Mode: http://cdpn.io/c/esrtc
Professor Mode: http://cdpn.io/p/esrtc

Our SMS feature will send you a short URL just to keep the text a bit shorter. Free users get the Full Page view, PRO uses get the Live View.

We could use link tag to expose these in the markup:

But we’re not sure what use it is. Anyone know?
