As you type, PowerPoint’s AutoCorrect feature automatically corrects common typos and spelling errors. How does PowerPoint know that a particular word is spelled wrong? Does it refer to some resource as a reference? Also, do you find some AutoCorrect options such as the capitalization of some words unnecessary? Several researchers working in different scientific fields actually have to use some words that cannot start with a capital letter, and the first thing they want to do is turn off the automatic capitalization.
