1. In the Office 2007 application that you use, click on ‘Office Button>(Office 2007 Application Name) Options’. For e.g. in Excel 2007, we would need to click ‘Office 2007>Excel Options’.
2. Click ‘Customize’. Now select the command you want to add to the Quick Access Toolbar and click ‘Add’.
3. You can see that the command that was added in the previous step has appeared in the Quick Access Toolbar.
