Superscript is a small symbol that will be quoted in writing papers now. Superscript is generally used to further explain the marked words or paragraphs, so it is often used to explain the meaning or source. Its description is generally at the bottom of the page or at the end of the book, but many people may not know how to type it before writing. The following are specific marking methods, hoping to help everyone when writing a paper. 1. First, open the Word file on the computer desktop and find the location that needs to be marked.

2. Enter "[1]" at the position where the mark needs to be added and select it.

3. Then click the "superscript" symbol in the font options under the start menu bar.

4. You can also click the "Extended" symbol in the lower right corner of the font bar.

5. Then check "superscript" in the pop-up window and click "OK".

6. At this point, we can see that the labeling in the cited literature has been completed.
