I'd like to create a horizontal separator and I can't find a function to help me do that. Can you help me?
On the official website, there is a user guide that might help you with this operation. I strongly recommend downloading it. It's in the PDF format. Access the page and then scroll down to the bottom of the page. Click the PDF icon to download it. Once downloaded, open the file and read. Alternatively, use the CTRL + F to look for the operation you need.
