Keyboard navigation makes you a better designer

Accessibility is often introduced as something to validate at the end of a project. Once the interface is designed and engineering is well underway, someone inevitably asks whether the experience can be used without a mouse. By that stage, keyboard navigation has become a compliance exercise, focused on fixing interaction issues rather than influencing how the product is designed in the first place.

I believe we should approach it differently.

For me, keyboard navigation isn’t simply about meeting accessibility standards. It’s one of the most valuable design exercises available because it forces us to think beyond individual screens and consider how an entire experience behaves. The moment you start navigating a product using only the keyboard, you’re no longer evaluating pixels or visual hierarchy—you begin evaluating structure, relationships and behaviour. Every press of the Tab key becomes a question: Does moving here next actually make sense?

Designers naturally spend a significant amount of time refining layouts, spacing and visual hierarchy, yet we often dedicate far less attention to how users actually move through those interfaces. Keyboard navigation exposes that gap almost immediately. A confusing focus order is rarely just an accessibility issue; it’s often a symptom of a deeper problem in the information architecture or interaction model. If users cannot navigate your interface in a logical sequence, there is a good chance the experience itself isn’t organised as clearly as you originally believed.

This becomes even more apparent when designing complex products or design systems. Every component exists in multiple contexts, interacts with other components and supports numerous states. Thinking about keyboard navigation early forces you to consider those relationships before they’re implemented. Questions that might otherwise remain hidden suddenly become impossible to ignore. Where should focus move when a dialog opens? Where should it return when it closes? How should nested menus behave? What happens after an error message appears? These aren’t edge cases—they’re part of the product experience, and keyboard navigation simply helps reveal them sooner.

Over the years, I’ve found that some of the most valuable product conversations have emerged from discussing keyboard behaviour rather than visual design. Walking through a user journey without touching a mouse often uncovers assumptions that nobody realised had been made. Missing states, inconsistent interaction patterns, ambiguous workflows and unclear user journeys all become significantly easier to identify because you’re forced to think about the complete experience rather than isolated screens. In many ways, keyboard navigation becomes a design critique of your own work.

This mindset is particularly valuable when building design systems. A component isn’t truly reusable because it looks consistent; it’s reusable because its behaviour is predictable wherever it appears. Keyboard interactions are therefore just as much part of a component’s API as its visual appearance. When designers define those behaviours from the beginning, they provide engineering teams with a far clearer specification while ensuring users encounter familiar, reliable interactions throughout the product.

Ironically, the more I design with keyboard navigation in mind, the less it feels like an accessibility exercise. Instead, it becomes a way of validating whether the product is fundamentally coherent. Accessibility is certainly one of the outcomes, but it isn’t the only one. Better user flows, stronger interaction models, more resilient components and fewer implementation surprises all emerge from the same design process.

Perhaps that’s why I believe every designer should spend more time navigating their own work without a mouse. Not because every user will, but because doing so forces us to think more critically about the experiences we’re creating. More often than not, the keyboard reveals design decisions that the mouse quietly lets us overlook.
