Minibars are a great new feature in Office 2013 that bring the tools you need to your work area based on the item you’ve selected on the page. For example, if you click an image, a minibar that contains image editing and formatting tools will appear. If you choose a table, the minibar will display tools you can use for editing, updating, and enhancing the table.
In your Office 2013 document, select some content, such as text, cells, or a picture.
Click the minibar icon near your selection.
If categories appear, click the one reflecting the task you want to accomplish.
Click your choice.
