+// 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.
