Use navigation bar in slide show (update)

A few years ago I wrote the following articles on how to use the navigation bar in PPT 2010.

In version 2013 a few things have changed.

The navigation bar now consists of 6 buttons. The first one lets you show the previous slide, the second one the following slide. When you click on the pen you can make annotations on the screen during the presentation.

Click on Laser Pointer and move the mouse, a red circle appears which you can move by dragging the mouse. This allows you to point to certain important areas on your slide.

When you choose Pen, start drawing by dragging with your left mouse button, be aware that the drawing will be rudimentary. You can't draw perfect straight lines or circles.
Finally you have the Highlighter. You can adjust the colour of the ink at the bottom of the menu and if need be use the Eraser to remove your annotations.

If you want to stop making annotations press the Escape key. Press Escape again and a choice will be offered to keep or remove the annotations.

If you choose to keep the annotations you can later select one and edit using the contextual tab Inking tools.
Once you activate the pen, you can use it on several slides, to navigate to the next slide you can use your keyboard (press N, PageDown, down arrow), or use the next button on your navigation bar in the left corner.

Using the fourth button lets you bring up the whole slide deck and jump to any slide in your presentation by clicking on it. If you do not want to change the slide just click the arrow on the top left of your screen.

The fifth button lets you zoom in on a part of the slide and pan around if you want.

Finally there is the More options button.

The Last viewed option lets you return to the last viewed slide quickly, useful when you hyperlinked to another slide and want to return where you left off.

The Custom show option there allows you to jump to a custom made show which contains only the slides you want to show in a chosen order suitable for a particular public. You must make the custom shows beforehand using the Custom Slide Show button on the Slide show tab.

The Show Presenter View allows you to see your next slide and your notes while you are presenting without the public noticing anything. See my previous articles on the subject:

Presenter view (2)

The Screen option allows you to make the screen white or black by pressing the W or B keys on your keyboard. This can be useful if one needs to focus the attention of the audience on something outside your presentation. You can of course hide the annotations and show the Windows taskbar if needed.

The Arrow Options allow you to influence the behaviour of the mouse pointer.

The Help option shows a summary of all keyboard shortcuts that are useful to navigate during the slide show.

The options Go to and Go to section have disappeared and replaced with The see all slides button (see above). If you have a presentation with sections you can choose the sections there.
