How to deselect one sheet in a spreadsheet after having selected several
Choose one of these two methods:
 * 1) Use the same operation as when you selected them:  + click on the tabs of the sheets to be deselected. This can prove tiresome if there are a significant number of sheets.
 * 2) Faster:  + click on the tab of an active sheet. All the other active sheets are deselected.
