Keyboard navigation
Use Tab and Shift+Tab to move between links and controls. Press Enter to activate links, and Enter or Space to activate buttons. In the three-part approach selector, Left and Right arrows move between chapters, while Home and End move to the first and last chapter. Escape closes open dialogs. The first keyboard link skips directly to the main content.
Motion and reading
The website follows your device’s reduced-motion setting. You can also choose Reduce motion in Reading options. Your choice lasts for the current browser tab. Scrolling remains under your control.
Light and dark themes
The circular theme button in the top-right corner switches between light and dark mode. We follow your device’s color preference until you choose a theme. Your choice is remembered on this device. Team rows respond to keyboard focus as well as pointer hover.
Read aloud
Reading options includes an optional read-aloud control. It reads the main page content with a local English voice, when your browser and operating system provide one. You can pause, resume, or stop at any time. It does not require microphone access. If no local voice is available, use your system’s screen reader or reading tools.
Screen readers and display settings
Pages use descriptive headings, labeled controls, and meaningful link text. Decorative visuals are excluded from the reading order. You can zoom using your browser and use your system’s contrast settings. The interactive approach diagram has a text explanation alongside it.
