Eye sea watt ewe mien?

>For example, in English we have a "shortcut," but I can't readily think of the opposite unless I use the German word "Umweg."

The opposite of shortcut is a longcut. Maybe not standard English, but certainly easy enough to come up with on your own and easily understood by whomever you are talking to. And a web search comes up with the following: http://www.urbandictionary.com/define.php?term=longcut

I thought that was very funny. I was sure you were pointing to a custom made kindle cover.
