The same reading options are available on every page, including Insights articles. Your choices are stored in this browser.
On every page
- Skip to content. The first Tab stop is a link that moves focus to the main text.
- Accessibility options. A control at the bottom left opens text size, high contrast, underlined links, and reduced motion. Reset clears those choices.
- Keyboard. Menus, the contact form, article filters, and diagram enlarge work from the keyboard. Escape closes the mobile menu, an enlarged diagram, and the options panel.
- Visible focus. The control you are on is outlined.
- Theme. The site follows your system light or dark setting. The sun and moon control in the menu switches it and remembers the choice.
- Browser zoom. The site does not block pinch-zoom or page zoom.
- Motion. If your system asks for reduced motion, animations and smooth scrolling are turned down. The options panel can do the same on this site.
Insights
On the Insights library, press / to focus search when you are not already typing in a field. Article diagrams can be enlarged with a click, Enter, or Space, and closed with Escape or the close button.
Known limits
Some articles are long technical pages. Diagrams include a text alternative where one was written with the figure. The contact form is delivered by an external service. If a page still blocks you, write to us and name the page and the barrier.
