Gwibber should have a shortcut to temporarily paste a URL without shortening it

Since we like the auto-shortening services as a must, but sometimes there's some addresses we want to keep as it is (http://daltux.com as example), there would be great if we could paste a single address without the need to open the menu, the preferences window, the correct tab and disabling the right checkbox only to avoid the shortening service that time and checking it on again to reactivate it. The current alternative to this boring process is to type the entire address, "ipsis litteris", when we want to avoid the shortening service only that time.

I believe a simple keyboard shortcut to paste a text bypassing the URL shortening could wonderfully do the job. I would say Ctrl+P, but it's already the shortcut to the Preferences dialog. What about Ctrl+U, perhaps?
