Insert Video (Movie) Clips
If you want to insert a video clip within your PowerPoint slide, spare a thought for why you would insert video clips in the first place. Most of the video clips are just added to grab attention. Fortunately, there are a few good reasons to adding video clips -- let us explore these, and then show you how you can add a video clip to your slide in PowerPoint 2013. Here are the good reasons.

Plot Area for Charts
In a chart, the Plot Area is the layer placed between the Chart Area and other chart elements such as Data Series and Gridlines. This layer typically also has the axes on its perimeter. Typically the Plot Area looks as if it is merged into the Chart Area because it is often transparent, and you can see the Chart Area through it. So, you may not be able to distinguish it from the Chart Area. This default status works well. However, you can format the Plot Area separately to highlight it. You can change its appearance by applying fills, borders, and effects with just a few clicks.

Drawing Parabolas
Several previous tutorials have explored the different drawing tools in PowerPoint 2013, and how they work -- we have worked with line drawing tools such as line, curve, freeform, and scribble. Using these line tools, you can draw almost anything in PowerPoint that you normally draw in high-end illustration programs. In this tutorial, you will learn how you can draw a parabola in PowerPoint 2013 using some of these drawing tools.

Edit Chart Data
When you insert a new chart in PowerPoint 2013, you might notice that an instance of the Excel sheet containing some dummy data for your chart pops up within PowerPoint -- you then change the data within that instance of the Excel sheet to auto-update the chart on your slide. However, this Excel instance that stores your data has no separate existence -- there's no separate Excel sheet that contains your data. In fact, this Excel sheet is stored within your PowerPoint presentation itself.

Drawing Hyperbolas
A Hyperbola is essentially composed of a smooth curve that is not too different from a parabola, but this smooth curve also has a mirrored image of itself so that the finished shape looks like two infinite bows. In thus tutorial we'll show you how you can draw a hyperbola using the drawing tools available in PowerPoint 2013.

Insert Video Clips from the Clip Art Pane
Unlike in PowerPoint 2010, there is no direct option to insert video clips from online sources such as Microsoft's clip art collection in PowerPoint 2013! What's more, Microsoft has removed its online clip art collection from its Office Online web site - so there's no way you can get those video clips from within a web browser and insert them in PowerPoint 2013 easily.

Add, Edit, or Delete Comments
When two or more people are involved in designing a presentation, there needs to be a channel for feedback. The Comments option works great for this purpose since it allows feedback without actually editing the slides themselves. A comment is a note that can be attached to any slide object or to a whole slide. You can add comments to write important notes for particular slide objects or for the slides themselves. This is a great way to provide feedback. Once a comment is added, you can edit the comment.

Slide Numbers within Slide Master
The moment you add a Slide Number to your slides in Normal view, you expect to see them immediately thereafter. However many times you may not see any Slide Number - or worse, you may see the Slide Number in just a few of the slides! To remedy this situation, you have to ensure that both the Slide Master and the Slide Layout for any given slide does contain the Slide Master placeholder - this is something you can do only within Slide Master view, as explained within this tutorial.
