skip_hidden_lines_backward
Usage
Void skip_hidden_lines_backward (Integer type);
Description
This function may be used to move backward across either hidden or non-hidden
lines depending upon whether the parameter
type is non-zero or zero.
If
type is non-zero, the Point is moved backward across hidden lines
until a visible line is reached. If
type is zero, visible lines will
be skipped instead. If the top of the buffer is reached before the
appropriate line is reached, the Point will be left there.
Note: The functions
up and
down are insensitive to whether or not
a line is hidden.
