Insert URL

I am new to WP and Atahualpa, although I love it.

I may be missing the obvious here, but when I am in the posting window of 3.4.3 (I think), above the window are icons to insert, image, music, video, media.

Would it be difficult to have an inset icon for "URL", so all I have to do is cut and paste an address rather than write out all the html code that is necessary?

Just a suggestion or I am an idiot and haven't found that yet.
