Why keyboard navigation matters more than it looks

Teams tend to reach for this after something has already gone wrong. Keyboard navigation is easy to treat as a detail, and that is exactly why it is worth a few minutes of attention.

Accessibility work almost always improves the experience for people who have no impairment at all. Most teams find the first pass takes an afternoon and the maintenance takes minutes a month.

What is actually at stake

Everything clickable must be reachable by tab. That sounds obvious written down. It is still the thing most often skipped. Most teams find the first pass takes an afternoon and the maintenance takes minutes a month.

Focus order should follow visual order. Small and consistent beats large and occasional here. Most teams find the first pass takes an afternoon and the maintenance takes minutes a month.

Common failure modes

Custom widgets are where keyboard support usually breaks. It is worth being explicit about, because assumptions differ quietly. The practical test is whether someone new to the project could tell, in a minute, that it had been handled.

How to tell if yours is fine

Most of it is correctness rather than charity: use the right element and much of it happens automatically. Three things worth confirming about keyboard navigation before you move on:

• Someone can say what the current setup is without going to look
• Everything clickable must be reachable by tab — and you know whether that is true here
• There is a way to tell whether the last change to this helped

None of this needs a rewrite. Most of it is a morning's work once someone decides to do it.
