Always spell-check your entire PowerPoint 98/2000 presentation to make sure everything is correct. Spelling errors will make even the most polished work look unprofessional.
If a misspelled word is found, select Change to use PowerPoint's suggested spelling or to change the word to the spelling of your choice; type your own spelling into the window.
Step4
Select Add to add the word to your spell-check dictionary, so that PowerPoint won't think it's misspelled next time. (This is useful for proper names and technical terms that aren't in the basic dictionary.)
