Some not very strong ideas...
Given this
"Currently correctly identified groups and who found them:
Shift, Option, Control, Alternate identified as (1) by M Oehm
Black, Red, Lane, Stock identified as (2) by ArgumentBargument"
Then how about
Jack: Flap Jack, Jack Sparrow, Jack Shaft and Jack Bond? (probably not because "Jack" works with too many things :/
Sorry about posting yet another "JACK"
or
BOND (James) drives an AMC Hornet
the GREEN Hornet is a comic book character
the giant SPARROW bee is a bee...
the United States NAVY have the F/A-18 Hornet, the USS Wasp, WASP class amphibious assault ships and others...
OR
Book, Green, Navy, Shaft:- Book Sleeve (the tacky paper cover on a hard back book), Green sleeves (horrible music), Navy Sleeves (are sown to the lower sleeve of their "blues" one of their three basic uniforms), Shaft Sleeves (a pipe connector thing used by engineers or plumbers I think)
