Good reason to use Xubuntu, Lubuntu or Linux Mint.
While I like the idea of shortcuts like these, they are best for launching applications, not for menus within applications. Once you get really good with an OS or application, you don’t even think about the key combinations necessary for simple tasks. ie: copy-paste, close window, quit program. I don’t think about I need to press to do those things, it just happens. Just like changing gears on a car, once you know how to drive, you just instinctively change gears, without having to tell your hands and feet what to do.
The Ubuntu HUD is a step away from this, in my opinion.
Ubuntu should put more energy into real human interface consistency instead.
