- // 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, wordsOnly, showToken, delay} 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. If wordsOnly is enabled, the matches will be
 
- // highlighted only if the selected text is a word. showToken, when enabled,
 
- // will cause the current token to be highlighted when nothing is selected.
 
- // delay is used to specify how much time to wait, in milliseconds, before
 
- // highlighting the matches. If annotateScrollbar is enabled, the occurrences
 
- // will be highlighted on the scrollbar via the matchesonscrollbar addon.
