Remove top links

You can remove all adminbar links by doing:

remove_action( 'admin_bar_menu', 'my_calendar_admin_bar', 200 );

There isn’t a way to selectively remove links.

Hello and thanks.
Sorry for noob level, but where do I put that code?

You generally need to built it into the ‘init’ action:

add_action( 'init' , 'my_remove_actions' , 15 );
function my_remove_actions() {
        remove_action( 'admin_bar_menu', 'my_calendar_admin_bar', 200 );
}

You could add that code into your theme’s functions.php file.
