     '-key'  will be easier to search for these users as well. It's also 
a low-cost arrangement. I trust adept API users will quickly suss out 
that the hyphen represents CLI. GUI users won't be entering the key 
string, only the values*, and casual CLI users will immediately 
recognize which entries pertain to options.
