First, the citation list with endnotes is like this, and the serial number does not meet the requirements of the paper format.

Second, the idea is to replace it with two steps. Ctrl+h opens the replacement interface.

3. Insert the cursor into the endnote area, change the superscript in the footnote area to non-superscript, and add [].

4. Insert the cursor into the text area, keep the superscript in the footnote area as superscript, and add []. E is a footnote with a special format, and searching for E means searching for all footnotes in a certain area; ^&； It's a placeholder. What you just searched for has been replaced now.

5. The methods of setting the search content as superscript are: more, format, font, and checking superscript.

6. The methods to set the search content as non-superscript are: more, format and font, and unchecking superscript.
