How can I edit a long URL in the Safari browser on my iPad 2?

I'd like to be able to edit a long url in the Safari browser on my iPad 2 running iOS 8.1.1. I can select it, but I can't scroll through it to add or delete something on the end. I generally copy/paste it into Notes, do the edit, then paste it back into the browser window, but that's a number of steps and becomes tedious.

Is there a way to do that type of edit inside the browser window?
