Making your website easier to navigate can significantly improve the reading experience. When visitors can move through content more smoothly, they are more likely to stay longer, explore more pages, and engage with your site.
One simple way to improve usability is to let readers move between posts using the keyboard’s left and right arrow keys. WordPress does not include this feature by default, but you can add it with either a code snippet or a lightweight plugin.
This can be especially useful for content that is meant to be consumed in order, such as serialized articles, chapter-based posts, documentation, journals, timelines, or smaller blogs focused on long-form reading.
In this guide, you will learn how to add arrow-key keyboard navigation in WordPress using two practical methods.
Why Use Arrow-Key Navigation in WordPress?
Keyboard navigation gives visitors a faster and more convenient way to move through your posts. Instead of scrolling around the page to find the next or previous article, users can simply press the arrow keys on their keyboard.
This works particularly well on websites where content is connected from one post to the next. For example, if you publish a story in multiple parts, post educational lessons in sequence, or organize articles in a series, arrow-key navigation can make the reading flow feel much more natural.
It can also improve the overall user experience by encouraging readers to continue exploring your content without interruption.

Method 1: Add Arrow-Key Navigation with WPCode
One of the easiest and safest ways to add keyboard navigation in WordPress is by using a custom code snippet.
Technically, you could place custom code directly inside your theme files, but that approach is not ideal. Even a small mistake in a theme file can cause errors or make the site unstable. A safer solution is to use a code snippet plugin that handles custom code in a more controlled way.
A popular choice for this is WPCode. It allows you to add custom snippets without editing theme files directly, which makes the process easier to manage and safer for most site owners.
To begin, install and activate the WPCode plugin from your WordPress dashboard.
After activation, go to the code snippets area in your admin panel and create a new custom snippet. Give the snippet a clear name so you can identify it later.
When setting the snippet type, choose Universal Snippet. This is important because the code includes JavaScript and PHP output together, so using a plain JavaScript snippet type may not work correctly in this case.
Then paste the following code into the snippet editor:
<script type="text/javascript">
document.onkeydown = function (e) {
var e = e || event,
keycode = e.which || e.keyCode;
if (keycode == 37 || keycode == 33)
location = "<?php echo get_permalink(get_previous_post()); ?>";
if (keycode == 39 || keycode == 34)
location = "<?php echo get_permalink(get_next_post()); ?>";
}
</script>This snippet listens for keyboard input and performs a page redirect when a matching key is pressed. The left arrow key moves to the previous post, while the right arrow key moves to the next post. It also supports Page Up and Page Down as additional shortcuts.
Next, choose the insertion location for the snippet. A site-wide footer location is usually the most suitable option because it loads the script across the front end of the site.
After that, select Auto Insert so the code runs automatically once the snippet is enabled.
Finally, switch the snippet from inactive to active and save your changes.
Once the snippet is live, visitors will be able to move between posts using the keyboard without needing any extra setup on the front end.
Method 2: Add Arrow-Key Navigation with a Plugin
If you prefer not to use custom code at all, then a plugin-based method may be a better fit.
A simple option is the Arrow Keys Navigation plugin. Its purpose is straightforward: it enables readers to use the left and right arrow keys to move between posts on your site.
To use it, install and activate the plugin from the WordPress dashboard just like any other plugin.
One advantage of this method is that it does not require any extra configuration. In most cases, the feature starts working immediately after activation.
However, it is important to understand its scope. This plugin is designed for post-to-post navigation, not full site navigation. That means it helps users move between blog posts, but it does not let them jump from one static page to another, such as from the homepage to the contact page.
If you want visitors to notice this new navigation feature, you can also display a small notice on your site. For example, you might add a message bar, popup, or inline note that tells readers they can use their keyboard arrow keys to move to the next or previous article.
Which Method Is Better?
If you want more control and prefer a flexible setup, the WPCode method is usually the better choice. It keeps the implementation lightweight and avoids editing your theme files directly.
If you want the fastest possible setup and do not want to deal with code at all, then the plugin method is the simpler option.
In both cases, the result is similar: readers can move through your posts more easily using their keyboard.
Arrow-Key Navigation for Sliders and Image Galleries
The two methods above are intended for navigating between posts. But arrow-key navigation can also be useful in other parts of a website, especially image galleries, carousels, and sliders.
If your goal is to let users move through images with the keyboard, then a standard post navigation solution will not be enough. In that situation, you need a WordPress gallery plugin or slider plugin that supports keyboard controls.
Many gallery and slider tools already include built-in arrow navigation, allowing users to switch slides or images using the left and right arrow keys.
This is especially useful for portfolios, photography websites, product showcases, tutorials, and visual presentations where keyboard-friendly browsing improves usability.
When choosing a gallery or slider solution, it is a good idea to look for features such as keyboard support, responsive layout, image optimization, accessibility settings, and alt text support.
When Arrow-Key Navigation Makes the Most Sense
This feature is not necessary for every type of website. On some blogs, visitors may never use it. But in the right context, it can noticeably improve the browsing experience.
Arrow-key navigation is often most useful for:
- Post series published in order
- Online books or chapter-style content
- Historical timelines or event sequences
- Educational lessons or tutorials
- Smaller content-driven blogs focused on reading flow
In those cases, making navigation quicker and more seamless can help users continue from one entry to the next without friction.
Final Thoughts
Adding arrow-key keyboard navigation in WordPress is a simple enhancement that can make your site feel more reader-friendly, especially when your content is designed to be explored in sequence.
You can implement it with a custom WPCode snippet if you want a cleaner and more flexible setup, or use a dedicated plugin if you prefer a no-code solution.
And if your focus is on images, portfolios, or sliders rather than blog posts, then a gallery or slider plugin with built-in keyboard controls will usually be the better route.
Used in the right context, arrow-key navigation can make your WordPress site easier to browse and more enjoyable to use.
