Squiggled

`Squiggled`

✖

Squiggled[expr]

displays expr with text underlined with a squiggly red underline.

✖

Squiggled[expr,color]

displays squiggly using the specified color.

Details and Options

Squiggled displays text with a wavy line in the underline position, such as is commonly used in spell checking.
Squiggled can use any option that is documented to apply at the style level. This includes font options such as FontSize, FontWeight, FontSlant, FontFamily, FontColor and Background.
By default, the typeset form of Squiggled[expr] evaluates to itself, including the Squiggled head. With the option StripOnInputTrue, the typeset form evaluates to expr without the Squiggled head. »
Squiggled[expr,color] is effectively equivalent to Style[expr,FontVariations{"Underlight"color}].
