Hello,
After racking my brains on how add an edit page button. I found that editUrl is missing from the CheatSheet. I added "/processwire/page/edit/?id=". $page->id, however I felt that wasn't right. After going on github and checking the default template I noticed that there was a editUrl function available.
Would be nice to see it added to the CheatSheet or in the API Documentation. "http://processwire.com/api/variables/page/"
Thanks,
