If the wavy red line under perceived spelling errors in PowerPoint are distracting and you would prefer to spell check in your own time, then it is no problem to change defaults and stop the red squiggles from appearing as you type.
These steps do not turn the Spell Check feature off, as PowerPoint still knows that there is a perceived spelling error in a word, it just won’t immediately flag it and you will simply need to run the Spell Check to have it pointed out for correction.
- Click the Office Button
- Choose Options.
- Once into your options select the Proofing category on the left.
- Under the When correcting spelling in PowerPoint section, check the option to Hide spelling errors.
- Click OK.
Reverse these steps if you wish to see spelling errors highlighted as you work.
