When typing, having to remove your hands from the keyboard to insert a symbol can be avoided by using a simple trick, though it only applies to the copyright, trademark, and registered symbols by default. These are set in AutoCorrect.
Instead of pausing to use the mouse to select Insert and then Symbol from the ribbon, type the following (add space after in Excel):
“c” for ©
“tm” for ™
“r” for ®
Another approach is to hold down the Alt key and enter a value using the numeric keypad. For example:
0169 for ©
0153 for ™
0174 for ®
To add a symbol to AutoCorrect, select File > Options > Proofing > AutoCorrect:
The default symbols are shown:
To add a symbol, use the Alt key and numeric pad. For example, to auto-correct (l) to become the sterling symbol, press Alt-0163. Click Add.
AutoCorrect is available in Word, Excel, and PowerPoint, but not Outlook.
