Controlling a presentation using wireless mouse is practical. Clicking the left mouse button takes you to the next slide, but right-clicking only displays the context menu, whereas you want to scroll back with it. You can disable the display of the context menu and go back to previous slides using right click.
For this, go to PowerPoint 203 and open ‘Tools > Options’ and disable the ‘Show menu on right mouse click’ option in the ‘Slide show’ field under the ‘View’ tab. Once you have confirmed this change with ‘Ok’, right clicking will always take you back to the previous slide during presentations. You can also enable this option again if you right-click to display the context menu.
In PowerPoint 2007 or 2010, click on the Office button, select ‘PowerPoint Options’ and then the category ‘Advanced’ to the left. This contains the ‘Show menu on right mouse click’ option in the ‘Slide show’ field.
