Newly inserted links are usually highlighted with a blue underline, so you can reset the highlighting or cancel the highlighting in other formats (even if the highlighting is cancelled, as long as the cursor moves over the text where the hyperlink is located, you will still be prompted "Hold down CTRL and click the mouse to follow the link").
Link operation:
1. Position the cursor where the hyperlink is inserted (or select a block);
2. Execute the Insert/Hyperlink command, select the name of the file (or bookmark) to be linked in the dialog box, and then click OK.
