I am not the most experienced with jquery so I came here hoping to get an answer. The problem I am having is how to hide all of the divs on a webpage, when clicking a keyboard button.

I know the basic code for hiding and showing a div would be: 

```
$(document).ready(function() {
    $("div").hide();  
    $("div").show();
});

```

What I don't know is if there is a easier way to hide every div on the webpage rather than just having a hundred `$("div").hide();` statements. I also am not sure how to monitor for a click on the keyboard and then hide and show various divs.

Thanks!
