The macro recorder, used to automate frequent tasks, is not available in Microsoft PowerPoint 2010. Instead, you can use Visual Basic for Applications (VBA) to create or edit macros.
To create or edit a macro by using Visual Basic for Applications, do the following (you can show the Developer tab if it is not available):
On the Developer tab, in the Code group, click Macros.
In the Macro dialog box, in the Macro name box, type a name for the macro.
In the Macro in list, click the template or the presentation that you want to store the macro in.
In the Description box, type a description for the macro.
Click Create to open Visual Basic for Applications.
Note: If you created a macro in a version of PowerPoint earlier than Office PowerPoint 2007 by using the macro reader, use Visual Basic for Applications to edit the macro.
