\bigbreak & \medbreak & \smallbreak ¶Synopsis, one of:
\bigbreak \medbreak \smallbreak
Produce a vertical space that is big or medium-sized or small, and suggest to LaTeX that this is a good place to break the page. (The associated penalties are respectively −200, −100, and −50.)
See \bigskip & \medskip & \smallskip, for more. These commands
produce the same vertical space but differ in that they also remove a
preceding vertical space if it is less than what they would insert (as
with \addvspace). In addition, they terminate a paragraph where
they are used: this example
abc\bigbreak def ghi jkl mno pqr
will output three paragraphs, the first ending in ‘abc’ and the second starting, after an extra vertical space and a paragraph indent, with ‘def’.
