There are a few ways to add lines to Instagram captioning, but the most common is by using the @ symbol. This will add a line between the caption and the image, making it look like a separate text block. Another way to add lines is by using the hyphen (-) symbol. This will add a line between the caption and the image, making it look like a separate text block. Finally, you can use the asterisk (*) symbol to add an extra line between each word in your caption. This will make it look like a separate text block.
