Tab moves you, and the ring says where you are
Press Tab to move forward through a screen and Shift + Tab to move back. Whatever you land on is drawn with a ring: a two-pixel outline in the product’s accent colour, with a small gap between it and the control so it stays legible against the surface underneath. That ring is the same on every control — buttons, links, text fields, the notes box on a finding, the navigation down the side of the screen. There is nothing to learn per screen: if something is ringed, that is what your next keypress acts on.The ring appears when you are moving by keyboard. Clicking a button with a mouse does not leave a
ring behind on it, which is why you may not have noticed it before.
Both themes
The ring is drawn to be visible against whatever is behind it, in the light theme and the dark one, on the page and inside a card. We measure it rather than judge it by eye: it has to be at least two pixels wide and clear the contrast bar the accessibility guidelines set for the boundary of a control, on every control, in both themes. A ring you cannot quite make out is treated as a bug, not as a preference. If you can find a control in Scaling where you cannot tell you are on it, that is worth telling us about.Skipping the navigation
Every signed-in screen starts with a Skip to content link. It is invisible until you Tab onto it as the first thing on the page, and then it appears at the top left. Press Enter on it and you land on the page’s own content, past the navigation. On a screen you visit repeatedly — the findings list, a source’s history — that is the difference between one keypress and a dozen.The controls you will meet
Confirming and dismissing a finding are both single buttons, so the whole of
judging a finding is reachable in a few presses
without ever leaving the keyboard.
