Subheads are useful when writing editorials with numerous sections. Linear has configured its system to automatically recognize when something is supposed to be a subhead. It will then automatically insert the correct formatting code as defined in your defaults.
How to Create Automatically Essentially, when looking for SubHeads, the system is looking for paragraphs less than 75 characters long - if found, the system will apply the SubHead format tags. Why 75 characters? Well 50 was too short and 100 was too long.
How to Create Manually You can declare a SubHead by putting <-- LPSH --> at the beginning of a line. Alternatively, you can declare a line is not a SubHead by placing <-- No LPSH --> at the beginning of the line; otherwise, if the SubHead controls have been invoked, the system will search through the editorial item looking for opportunities to format SubHead information.
Purpose This feature allows your editorial to have different body parts and to allow the visitor to visually skip to the sections they find important. SubHeads also divide am editorial making it visually more appealing.
