Unable to see all items on screen


I thought i was saving myself some time by copying a button from a previous page to put onto this page but when I pasted it i couldnt see anything. It was only when I run it to see what it all looked like i spotted three buttons at the bottom of the page but i cannot see or get to them within the editor. How can i scroll\move the page to see them?

Forget it, just use the arrow keys when something is highlighted
