## Keyboard Shortcut

In this example we show how to create a keyboard shortcut for an action.

We start with a simple button that loads some content from the server:

```html
<button hx-trigger="click, keyup[altKey&&shiftKey&&key=='D'] from:body"
        hx-post="/doit">Do It! (alt-shift-D)</button>
```

Note that the button responds to both the `click` event (as usual) and also the keyup event when `alt-shift-D` is pressed.
The `from:` modifier is used to listen for the keyup event on the `body` element, thus making it a "global" keyboard
shortcut.

You can trigger the demo below by either clicking on the button, or by hitting alt-shift-D.

You can find out the conditions needed for a given keyboard shortcut here:

    });
    
    onPost("/doit", function (request, params) {
        return "Did it!";
    });
