 ## Examples
 
-The following example provides functionality to toggle a popover on and off by pressing a particular key on the keyboard.

+### Simple auto-popup
+
+This is a slightly modified version of the [Toggle Help UI Popover Example](https://mdn.github.io/dom-examples/popover-api/toggle-help-ui/).
+The example toggles a popover on and off by pressing a particular key on the keyboard (when the example window has focus).
+
+The HTML for the example is shown below.
+This first element defines instructions on how to invoke the popup, which we need because popups are hidden by default.
+
+```html
+<p id="instructions">
+  Press "h" to toggle a help screen (select example window first).
+</p>
+```
 
-First, some HTML:
+We then define a `<div>` element which is the popup.
+The actual content doesn't matter, but note that we need the [`popover`](/en-US/docs/Web/HTML/Global_attributes/popover) attribute to make the `<div>` into a popover so that it is hidden by default (or we could set this element in the JavaScript).
 
 ```html
-<div id="mypopover">
+<div id="mypopover" popover>
   <h2>Help!</h2>
 
   <p>You can use the following commands to control the app</p>

-And now the JavaScript to wire up the functionality:
+The JavaScript for the example is shown below.
+First we check whether popovers are supported, and if they aren't we hide the popover `div` so that it isn't displayed inline.
 
 ```js
+const instructions = document.getElementById("instructions");
 const popover = document.getElementById("mypopover");
 
-document.addEventListener("keydown", (event) => {
-  if (event.key === "h") {
-    popover.togglePopover();
-  }
-});
+if (!HTMLElement.prototype.hasOwnProperty("popover")) {
+  popover.innerText = "";
+  instructions.innerText = "Popovers not supported";
+}
 ```
 
+If popovers are supported we add a listener for the `h` key to be pressed, and use that to trigger opening the popup.
+We also log whether the popup was open or closed after the call, but only if a `true` or `false` was returned.
+
+```js
+if (HTMLElement.prototype.hasOwnProperty("popover")) {
+  document.addEventListener("keydown", (event) => {
+    if (event.key === "h") {
+      popover.togglePopover();
+    }
+  });
+}
+```
+
+<!-- modifications to code once togglePopover() returns boolean
+      const popupOpened = popover.togglePopover();
+
+      // If not undefined, you can check if popover is opened or closed.
+      console.log(`popupOpened: ${popupOpened}`)
+      if (popupOpened === true) instructions.innerText += `\nOpened`;
+      if (popupOpened === false) instructions.innerText += `\nClosed`;
