My personal experience is that the noun in the phrase "just a _ away" is necessarily based on a verb.
Hi. I have just found an example which seems to break this rule.The standard advertising phrase is "is just a <quick action> away".
The bold part is not a quick action. So why does this example work?I know most of our operatives haven’t been trained in the soft touch, and I’ll be blunt: the last thing we need is somebody thinking this is Afghanistan and smacking a civilian around. We’re one YouTube video away from this whole thing blowing up in our faces, so we have to maintain our operational profile throughout.
