Keyboard Shortcut problem in P2 Theme Single.php

Hi guys,
I have a little problem with my P2 1.2.3 theme version.
The problem is that “Keyboard Shortcut” works correctly in index (index.php) and pages (page.php) but it doesn’t work in single post page (single.php). when I click the shortcut button the popup appear but the keyboard command doesn’t works.

I’m running the website in local with easyphp.
Does anybody have the same problem? How I can resolve?
Sorry for my bad english ??

Thanks.
