Most presenters stick with the mouse when giving their presentations, which works fine for advancing the presentation but leaves them stuck fumbling with the context menu and its submenus when they need to execute any other command. If you put in the modicum of effort required to learn the keyboard shortcuts that PowerPoint provides for running a slide show, you can control the presentation faster and more easily, which gives a more professional appearance to your presentation.
