If it's in MS Word and you're editing a list but want to add line-breaks without causing it to move to the next list-item, then simply hold down the SHIFT key while hitting ENTER. It will make a line break without exiting out of the current list item.
Either the enter key or the tab key
Manual line break
To insert a line break in HTML, use the <br> tag where you want the break to occur. In Markdown, you can create a line break by ending a line with two spaces and hitting enter. In programming languages like Python, you can use \n within a string to indicate a line break. For word processing applications, pressing "Enter" typically creates a new line.
Press the Enter key two times.
