selection key possible

[Disco]

is it possible to select more than one name via the selection keys? i use "namecontains" for one unit, but i want to include more than one name. say i have tech 1 tech 2 bombers. i want to hit "shift+ctrl B" and have all bombers selected.

tech 1 "shadow"
tech 2 "hurricane"

namecontains_"shadow","hurricane"+ (<<< something like that?)

i dont know the syntax, and i dont know if its even possible to use more than one unit name
