Macros are great tools for saving time when creating PowerPoint presentations, but their efficiency can be even more improved if they have a shortcut key command assigned to them. For the remainder of this guide, we’ll assume that you have the OfficeOne Shortcut Manager add-in installed and available for use in PowerPoint 2007. If you don’t have this done yet and need some help with that process, refer to Part 7 of this series.
Begin by opening the Add-Ins tab on the PowerPoint ribbon and selecting Customize Shortcuts.

When the Customize Shortcuts window opens, choose Macros from the Categories list. Then, scroll through the available macros from the Commands list, and pick the macro to which you want to assign a shortcut.

Next, click on the box next to Assigned Shortcut to Command. When you perform this action, the only change you will see at first is the cursor present in this box next to the word None. To change this to the shortcut key sequence you would like to use for the macro, simply enter the command on the keyboard. As you type the sequence, it will appear in the box. In the example shown in this screenshot, we’re assigning the command Alt + 2 as the shortcut for the selected macro.

When finished, click OK to continue. This will close the Customize Shortcuts window and return you to your PowerPoint presentation. Your shortcut is now set up and ready to use.
