Microsoft Office Visio automatically customizes menus and toolbars based on how often you use the commands. When you first start a Visio program, only the basic commands appear. As you work, the menus and toolbars adjust so that only the commands and toolbar buttons you use most often appear.

To look for a command that you don't use often or have never used before, click the arrows at the bottom of a menu to show all the commands. You can also double-click a menu to expand it. When you expand one menu, all of the menus expand until you choose a command or perform another action. When you click a command on the expanded menu, the command is immediately added to the short version of the menu. If you do not use the command often, it is dropped from the short version of the menu.

Toolbars can be positioned next to each other in the same row. For example, the Standard toolbar is positioned next to the Formatting toolbar when you first start Visio. When you put multiple toolbars in the same row, there may not be enough room to display all of the buttons. If not, the buttons that you have used most recently and most frequently are displayed.

You can resize to display more buttons, or you can show all buttons on a toolbar. To see a list of buttons that won't fit on a built-in, docked toolbar, click Toolbar Options at the end of the toolbar. When you use a button that is not displayed on the toolbar, that button is moved to the toolbar, and a button that has not been used recently is dropped to the Toolbar Options list.

You can customize menus and toolbars; you can add and remove buttons and menus on toolbars, create your own custom toolbars, hide or display toolbars, and move toolbars. You can customize the menu bar the same way you customize any built-in toolbar―for example, you can quickly add and remove buttons and menus on the menu bar―but you can't hide the menu bar.
