Compiling a PowerPoint presentation may mean grabbing for information from a number of sources. When you want to give credit to your sources through footnotes, inform readers of proprietary content through copyrights or add additional characters to a slide, you'll need to insert symbols. Like much in PowerPoint, registered symbols are automated and waiting to be added to your slides. Treat registered symbols like other textual characters and enhance your slideshow.
While there is one symbol that claims its namesake as the symbol for something being registered – the capital "R" in a circle – a collection of registered symbols is available in PowerPoint. Some may be more familiar than others, such as the superscript "TM" for trademark and the capital "C" in a circle for copyright, while others may look as if they're written in another type of alphabet.
Locate registered symbols off of PowerPoint's "Insert" tab. Click the "Insert" tab to open its corresponding ribbon. At the end of the ribbon's right side is the omega symbol. Click the small drop-down arrow under the omega to open the "Symbol" menu, consisting of 20 quick-add symbols from alpha to omega and others in between. The "More Symbols" link opens the "Symbols" window where full sets of fonts are available with additional symbol options.

When you click one of the symbols in the drop-down menu, PowerPoint assumes you want to add it exactly where your cursor is presently at. To note something on a slide is copyrighted, for example, type the term and, without adding any additional space or moving the cursor, click that registered symbol. There is no "Insert" or "Add" button; as soon as you click, PowerPoint adds it in. Click multiple times to add multiple instances of that symbol. To put the symbol elsewhere, highlight and copy or cut it just like any other character.
PowerPoint auto-formats the symbol when it inserts it into the text boxes, but you're not stuck with the way the symbol appears. Change formatting just as you would any other character. If you've clicked on the registered symbol, for example, but want it to appear in the traditional superscript format, simply highlight the symbol, right-click it, click "Font" and check the superscript box. Change size, color, position and font the same way.
