Suppose you are typing, you make a mistake, and you see the red wavy underline.
Suppose you correct the mistake, but meanwhile you've already lost the beat and the idea. To avoid these distractions, you can disable spell checking and manually check spelling when you're done typing. It is done like this.
Click File > Options > Proofing , clear the Check spelling as you type check box, and click OK .
To activate spell checking again, repeat the process and select the Check spelling as you type check box .
To check spelling manually, click Check > Spelling and Grammar .
But remember to turn on spell checking again. Spelling and grammar mistakes can seriously undermine what you're trying to communicate, especially if your boss, or your teacher, or that HR person sees them.
