     # reactive_selectors is a list of jQuery selectors meant to let appear tag context search by selecting text.
     # Example of list : [ '.any_class', '#any_div .p_class', '#another_selector' ]. Write [ 'document' ] if you want the whole document/page to be reactive.
     # Do not define reactive_selectors if you want nothing to be reactive.
