        # action = kwargs['action'] if 'action' in kwargs else 'CamelCase' # author dotcoo
        regions = self.view.sel()
        for region in regions:
            if region.empty() :
                region = self.view.word(region.begin())
            sel_text = self.view.substr(region)
            if action == 'CamelCase':
                sel_text = sel_text[0:1].upper() + re.sub(r'(_[a-z])', lambda m: m.group(1)[1:].upper(), sel_text)[1:]
            elif action == 'CamelCaseVariable':
                sel_text = sel_text[0:1].lower() + re.sub(r'(_[a-z])', lambda m: m.group(1)[1:].upper(), sel_text)[1:]
            elif action == 'Underscore':
                sel_text = re.sub(r'([A-Z])', '_\\1', sel_text).lstrip('_').lower()
            self.view.replace(edit, region, sel_text)
