Click the tab of the first worksheet, hold the Shift key
down and click a second tab. All the worksheets between
those two endpoints (inclusive) have been selected--and
you can print them, print preview, etc. The selected
sheet tabs will appear slightly whiter than the non-
selected sheet tabs.
If you want particular sheets, then CTRL + click on each
of the sheet tabs.
To unselect the sheets, click on a different sheet tab
(not holding the Shift or CTRL key down). Or rightclick
one of the sheet tabs within your selection and select
Ungroup sheets from the resulting popup.
