If you need a keyboard shortcut to open the preview in wordpress. Just add the function to your function.php

function add_custom_keyboard_shortcut_jquery() {	?> < script type=" text/javascript" > jQuery(document).keydown(function(event) {			if ((event.metaKey || event.ctrlKey) & & event.which === 89) {				event.preventDefault(); jQuery('#post-preview').click(); }
}); < /script> < ?php
}
add_action( 'admin_head-post.php', 'add_custom_keyboard_shortcut_jquery' ); add_action( 'admin_head-post-new.php', 'add_custom_keyboard_shortcut_jquery' );
