Presentations created in Microsoft's PowerPoint can be continuously looped by enabling an option in the slide show settings. This means the presentation will begin again from the first slide, immediately after the last slide, looping infinitely until the slide show is aborted by the user. Continuously looping presentations are useful in a variety of scenarios, such as information displays that are left unattended for long periods of time.

Configuring the Loop Setting
With a presentation open in PowerPoint, the loop setting can be found by clicking the "Set Up Slide Show" icon under the "Slide Show" heading on the ribbon at the top of the screen. The subsequent dialogue box offers a range of choices -- tick the top check box labelled "Loop continuously until 'Esc'" to enable the infinite loop option the next time the slide show launches. Click "OK" to confirm your choice and apply the setting.
Other Slide Show Options
A range of other options are available on the Set Up Show dialogue box. It's possible to switch between full-screen and windowed modes for the slide show, determine which slides in the presentation are displayed. This is useful if you only want to show a subset and choose whether to advance the slides manually -- on a mouse click -- or automatically using the timings configured with each slide. Transitions and slide durations can be customised on the "Transitions" tab of the PowerPoint ribbon, while the "Animations" tab enables you to set up effects for the individual elements within each slide.
Launching a Presentation
Click the "Slide Show" icon in the lower right-hand corner of the screen to launch a full-screen presentation in PowerPoint. The "From Beginning" and "From Current Slide" icons on the "Slide Show" tab at the top of the screen can also be used. Alternatively, press the "F5" key on the keyboard. The slide show will run based on the settings you have configured. If you have activated the continuous loop setting, the slides will continue to be displayed in order until you press the "Esc" key.
