\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 -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’.
