Final answer:
To turn off modern comments in Word, one might search for an option in the Word Options menu, though if not available, the feature may be fixed. Comments are added by selecting text and clicking 'New Comment,' then typed into a box. Comments are deleted by clicking in the comment box and selecting 'Delete.'
Step-by-step explanation:
If you’re looking to turn off modern comments in Microsoft Word, and revert to the classic comment system, please note that as of my last knowledge update in March 2023, Microsoft had been introducing the modern comment system as part of an ongoing update to Word across various platforms. If there is an option available, it would typically be found within the Word Options menu under the General or Review settings. You could look for a toggle to switch between modern and classic comment styles. However, if the version of Word you are using does not provide an option to toggle this feature off, you may not be able to revert to the classic comments.
To add a comment, highlight the text you wish to comment on, click on New Comment in the tools ribbon, and type your comment in the new box that appears in the margin. Once done, click outside the box to save the comment. To delete a comment, click in the comment box and select Delete next to the New Comment button in the tools ribbon.
