How to copy a worksheet, WITHOUT linking it to the original workbook?

A simple one for you, but again my Google skills seem lacking. This must be common practice but until one knows the key combination...

I have created a summary sheet with lots of formulas which analyse other sheets in a workbook. I want to copy this summary sheet to a seperate workbook to use as a template.

Of course, the copying process always links the new (template) sheet to the original workbook it was copied from. How does one copy without forging this link? All I want are the formulas copied across totally unchanged; I really *don't* want to manually edit 50 or so formulas!

Again, thank you.
