$show-region(5)
$show-region(5)$show-region - Enable the hilighting of regions
$show-region flag; Default is 1
$show-region enables or disables the current region hilighting, normally associated with mouse interaction in a buffer. Region hilighting occurs between the mark (see set-mark(2)) and point (current cursor) positions within the current buffer. An argument n of 0 disables region hilighting, an argument of 1 enables region hilighting between the two positions. If it is set to 3 then region hilighting will be enabled and a defined region (created using copy-region(2)or yank(2)) will continue to be hilighted until the region is changed.
A defined region can be redisplayed (if still valid) using the command show-region(2). The color of the region hilighting is defined by add-color-scheme(2) and is determined by $buffer-scheme(5), $global-scheme(5) or $buffer-hilight(5).
show-region(2), $buffer-hilight(5), $buffer-scheme(5), $global-scheme(5), $buffer-scheme(5), add-color-scheme(2), set-mark(2).
