I was at a presentation recently and noticed that there was a spelling mistake on the slide. Unfortunately this is not uncommon, but this mistake caused me to investigate a little further. The spelling mistake was in the axis of a graph. My question was, “Does PowerPoint spell check axis labels?” My testing in PowerPoint 2003 revealed that it does not! This can be a shock to those who rely on the spell check feature (let’s not get into why you can’t rely on the spell check anyways). And it is one more reason why you need to carefully check every piece of text on your slides before show time. Spelling mistakes reduce your credibility and hurt your ability to get your message understood and acted upon.
