Selecting Excel tabs - without tab name

How can a macro select "all" tabs (or specific ones) without having to write in each tab name? My tab names might change, so I'd like to be able to select them all, or select sheets #2-6, 8, 11-21, etc., and print?

Thanks much!

worksheets can be refered to by index as well as by name

VB Code:

Sheets(Array(1,3,5,7,8)).Select
ActiveWindow.SelectedSheets.PrintOut Copies:=1, Collate:=True

So simple! Thanks!
