When editing pages, all I see is the SAVE button.

What if one wants to cancel and abandon any changes?  ESC or Cancel Button for this?

Going back to View page without saving works OK.

I managed to add Cancel button on edit form. Near the end, in line:
[center][button submit]Save[/button][/center]

paste this:
[center][button submit]Save[/button] [url="{{this_path}}"][button]Cancel[/button][/url][/center]

It should link back to View page.
