/me moves cursor over to the scroll bar only to be intercepted by a pop-up menu containing a logo, helpfully labelled "Logo".

You have to make sure the article body has the keyboard focus first though (e.g. by clicking somewhere on the text); it would be nice if they'd somehow arrange for that to happen by default...
