wordpress Turn On More Buttons in the WordPress Visual Editor
These buttons (like one for adding an <hr> tag) aren't there by default in the WordPress visual editor, but you can turn them on pretty easily. This is code for your active theme's functions.php file, or make a functionality plugin.
function add_more_buttons($buttons) {
$buttons[] = 'hr';
$buttons[] = 'del';
$buttons[] = 'sub';
$buttons[] = 'sup';
$buttons[] = 'fontselect';
$buttons[] = 'fontsizeselect';
$buttons[] = 'cleanup';
$buttons[] = 'styleselect';
return $buttons;
}
add_filter("mce_buttons_3", "add_more_buttons");
