Win10 provides Windows 7-style Control Panel views that have a "Cancel" button to dismiss a screen without saving changes. Is there a similar option in the Windows 10-style settings views? I can't find it via manual inspection, Google search, or SU search in windows-10.
Use case: I just opened the new-style Power & Sleep settings and tried to scroll with the keyboard. However, I didn't realize that the "On battery power, turn screen off after" dropdown had keyboard focus. I therefore have changed the timeout but have no idea what it was before! I would like to cancel but can't figure out how.
I agree this is not a very significant problem :) . However, I would like to be prepared should I need to cancel a more important change in the future.
