-jn or --jump-target=n
Specifies a line on the screen where the "target" line is to be
positioned. A target line is the object of a text search, tag
search, jump to a line number, jump to a file percentage, or
jump to a marked position. The screen line may be specified by
a number: the top line on the screen is 1, the next is 2, and so
on. The number may be negative to specify a line relative to
the bottom of the screen: the bottom line on the screen is -1,
the second to the bottom is -2, and so on. Alternately, the
screen line may be specified as a fraction of the height of the
screen, starting with a decimal point: .5 is in the middle of
the screen, .3 is three tenths down from the first line, and so
on. If the line is specified as a fraction, the actual line
