Brief: Control the style of the region.
Symbol: modus-themes-region (‘choice’ type, list of properties)
Possible values are expressed as a list of properties (default is nil or
an empty list). The list can include any of the following symbols:
no-extend
bg-only
accented
The default (a nil value or an empty list) is a prominent gray
background that overrides all foreground colors in the area it
encompasses. Its reach extends to the edge of the window.
The no-extend property limits the region to the end of the line, so that
it does not reach the edge of the window.
The bg-only property makes the region’s background color more subtle to
allow the underlying text to retain its foreground colors.
The accented property applies a more colorful background to the region.
Combinations of any of those properties are expressed as a list, like in these examples:
(no-extend) (bg-only accented) (accented bg-only no-extend)
The order in which the properties are set is not significant.
In user configuration files the form may look like this:
(setq modus-themes-region '(bg-only no-extend))
