 * Hello,
 * For educational purposes, I need to add a tinymce button in a frontend editor
   which enable insertion of equations for student that do not know anything about
   latex. In wordpress the plugin [Mathtex equation editor](https://wordpress.org/support/plugin/mathtex-equation-editor)
   allows this feature very well in back-end edition of posts by adding a tinymce
   button.
 * However this button do not remains on front-end edition. The frontend editor 
   in use is defined in another plugin (Anspress). And adding ‘mathTex’ button in
   the following class function is apparently not sufficient.
 *  ` public function editor_buttons( $buttons, $editor_id )
    { if(is_anspress())
   return array( ‘bold’, ‘italic’, ‘underline’, ‘strikethrough’, ‘bullist’, ‘numlist’,‘
   link’, ‘unlink’, ‘blockquote’, ‘pre’, ‘mathTex’);
 *  return $buttons;
    }`
 * I have spent hours trying to figure out how to achieve this but adding filters
   to hook mce_external_plugins function and others do not succeeded…
    Can anyone
   suggest me how to display this button in front-end editor also? Thanks a lot.
