-// Highlighting text that matches the selection
-//
-// Defines an option highlightSelectionMatches, which, when enabled,
-// will style strings that match the selection throughout the
-// document.
-//
-// The option can be set to true to simply enable it, or to a
-// {minChars, style, showToken} object to explicitly configure it.
-// minChars is the minimum amount of characters that should be
-// selected for the behavior to occur, and style is the token style to
-// apply to the matches. This will be prefixed by "cm-" to create an
-// actual CSS class name. showToken, when enabled, will cause the
-// current token to be highlighted when nothing is selected.
