Once more has obtained input, it displays as much as can fit on the current screen and waits for user input to advance, with the exception that a form feed ( ^ L ) will also cause more to wait at that line, regardless of the amount of text on the screen.

This use of the form feed character is not supported by all newsreaders, and is not standardized, although it has appeared in a draft of a Usenet Best Practices document by the IETF's USEFOR working group, as a feature that user agents should ( but are not required to ) support.
