customize toolbars

many toolbar buttons you never used. You can add some mostly used buttons for example "Paste" or "Print Preview" in your browser toolbar or remove with same option.
If you are using Internet Explorer then right click on the empty area of the toolbar and select the option "Customize". Here you will find a list of options in left and right panel, if you want to add any toolbar button then simply highlight it from the left panel and click on the "Add" button. But if you want to remove any toolbar button then first highlight it from the right panel and click on the "Remove" button.
