The squiggly red underline that shows up on some words indicates that PowerPoint considers those words to be misspelled! But that's not always the truth -- your spelling may be accurate but PowerPoint merely indicates the spelling error because that particular word may not be part of its vocabulary. Let's explore this more -- PowerPoint considers some medical or legal terms which are not commonly used, as misspelled words. To avoid this, you need to teach PowerPoint to spell those words -- in other words, you must enhance PowerPoint's custom dictionary. Of course, not only can you teach PowerPoint how to spell medical words, but you can also teach the program how to spell words that enhance lexicons in various other subjects such as research, law, computing, etc.

Loading and Using Custom Dictionaries
Have you ever wondered what happens behind the scenes whenever you do a spell check in PowerPoint or any other Microsoft Office program? PowerPoint looks at each word you have typed and matches those words with the entries listed within its dictionary. If the dictionary does not contain any of the words in your slides, it goes ahead and marks that word as misspelled. Then it offers you suggestions for changing those supposedly misspelled words to other similar words that can be found within its dictionary.

Resizing Shapes
Once you insert your shapes on a slide, you may realize that it's not the perfect size -- did you want it larger, or a wee bit smaller? However you want your shapes resized, it's easy to make the size change in a jiffy, right inside PowerPoint 2013. Like most Microsoft Office programs, PowerPoint follows the concept of selection, then action -- so the first thing you need to do for a shape that you want resized is to select it! Any shape that is selected shows several handles.

Smarter Guides
Do you notice that any object you move, resize, or align in PowerPoint 2013 actually helps make your task easy! Move it a little closer, resize a wee bit, or even try spacing slide objects and the screen shows all sorts of helpful indicators in the form of dotted lines. The red, dotted lines are essentially Smart Guides -- these made their debut in PowerPoint 2010 and allowed you to position objects easily -- now in PowerPoint 2013, they are a whole lot smarter and even let you see how much further you need to drag so that one object on the slide is as wide as another.

Rotate Shapes
When you insert any shape in your PowerPoint slide, more often than not you will want to make some changes to the default shape that you end up with. Mainly, you may want to resize and rotate the shape -- this is something we do a lot in our everyday life -- like rearranging our work desks, or even changing the position of our favorite chair so that we feel more comfortable. Similarly, all objects on your slide need to be arranged in a way that feels appropriate -- rotation is one way of making this change happen. In PowerPoint 2013, rotation can be applied in more than one way.
