Imagine this scenario — you have created a specialized, medical presentation that’s full of squiggly, red, underlined words! These squiggly underlines indicate what PowerPoint considers to be as a misspelled word! Don’t blame PowerPoint, because its medical skills are somewhat limited — we do know that almost all the words in your medical presentation are perfectly valid as far as spelling is concerned. The silver lining here though is that you can teach PowerPoint to spell those words — and 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. Any changes you make by adding new spellings of words in PowerPoint will also influence spell checking in other Microsoft Office programs such as Word, Excel, Outlook, etc.
