| ;**newline** |
| :A "cuttink" mark, usually inserted by pressing the return/enter key, which is both a character that creates a new visual line and, in most cases, a tag that starts a new line-component (see comment about this below under 'page structure'). |
| ; **logical & visual newlines** |
| :A newline is a mark usually inserted by pressing the return/enter key. A newline is both a plain character that creates a new visual line and, in most cases, a tag that starts a new line-component (see comment about this below under 'page structure'). \\ |
| Logically enough, a newline preceeded by an escape (plain-character) tag becomes a visual newline : it loses its tag function but remains a plain character, thus starting a new visual line without marking the end of the logical line. |
