As you continue to work with Google Spreadsheets, you'll want to return to spreadsheets you previously worked with. To open a spreadsheet you created during a previous session, either click the Open link or select File, Open. Either action opens the Open a Spreadsheet dialog box, shown in Figure 11. Click the spreadsheet you want to open from the list presented; that spreadsheet now opens in a new browser window.

A new browser window opens only if you have a saved spreadsheet currently open. If you have a new, blank spreadsheet open, the spreadsheet you select will open in the current browser window.
