Diagrams

Diagrams are made of buttons and focusable regions, so everything is reachable by keyboard.

KeysWhat happens
Tab to the diagram areaFocuses the scrollable region. Arrow keys scroll it when it is wider than the screen
Tab to Open full size, then EnterOpens the diagram in a full-screen view. Esc or the Close button leaves it
Tab to a step control, then Right or DownNext step (step-through diagrams)
Left or UpPrevious step
HomeBack to the first step
Tab to a box in a diagram, then EnterShows the details of that box (hover details work on focus and click too)

Focus the step buttons first: the arrow keys only act while focus is inside the step controls. Nothing on the diagrams moves by itself, so there is nothing to turn off for reduced motion.

Every diagram also has a Text version of this diagram section that opens with Enter.
