Remove a specific TinyMCE item from the WordPress editor

When filtering a row of TinyMCE buttons, here’s a way to remove a specific button by name. This is useful for cases where you’re editing the default editor instead of declaring your own editor. In this example, we’ll remove the underline button from the second row:

function my_mce_buttons_2( $buttons ) {
	$index = array_search( 'underline', $buttons );
	if ( $index !== false ) { unset( $buttons[$index] ); }

	return $buttons;
}
add_filter( 'mce_buttons_2', 'my_mce_buttons_2' );

Drop that code in your functions.php file to remove a specific item from your WordPress editor buttons. For more information about the individual TinyMCE toolbars available see this codex page. To list all buttons by name for a given toolbar, temporarily add print_r( $buttons ); to your filter callback function.
