Customizing Menu Commands
By default, PowerPoint menus tailor themselves to the way you work. Initially, only the most commonly used commands appear on the menus (see Figure 20.17). If you click the Expand button (the double arrow) at the bottom of the menu or wait a few seconds, the menu expands to include other commands you have used rarely or not at all (see Figure 20.18). If you begin to use a command regularly, PowerPoint then adds that command as a regular menu item.
Although customizing menus is activated by default in PowerPoint, this option can be turned off.
