Scroll down to the “Show document content” section and select an option from the “Field shading” drop-down list. Click “Advanced” in the list of items on the left. On the backstage screen, click “Options” in the list of items on the left. We’ll show you where to change this setting for shading on fields. However, if you’re going to share the document with others or use it in a presentation, you might want to turn off the field shading completely so it’s not distracting for others. The shading on fields can be helpful to make it easier to find the fields in your document. When you select an entire field, it is both shaded and highlighted.
By default, when you insert a field into a document, it is shaded (not highlighted) when you put the cursor anywhere in the field. There are a lot of built-in fields available in Word, such as the current date, the date a document was last saved, the file name, and the number of words in a document. For example, when you insert page numbers into the header or footer of a document, Word actually creates a field that inserts the correct page number on each page. To turn off highlighting, click the highlight tool again.
Now, whenever you select some text, the highlighting style you chose is automatically applied to the text. Fields in Word are bits of code that are placeholders for data that changes. Use highlight mode: Click the Highlight button (so it turns gray), click the down arrow next to the Highlight button, then choose a highlight color, underline, or strikethrough.
