You can submit multiple inputs (via id) with the ajax() function, so if you
give your checkbox inputs id's (e.g., id='title' and id='body'), you should
be able to do:
ajax('callback', ['keyword', 'title', 'body'], 'target')
and in the controller, access request.vars.keyword, request.vars.title, and
request.vars.body (I think title and body will be None if they are not
checked).
