Keyboard operability
Keyboard operability makes tasks possible without a mouse. Actions must be reachable through a clear sequence of controls.
Complete tasks without a mouse
Keyboard operability means that an interface's functions can be used through a keyboard interface. This includes entering data, selecting options and opening or closing dialogs. It does not require a separate keyboard shortcut for every action.
In an example customer portal, you reach “Change delivery address” with Tab, open its dialog with Enter and then move to the fields. If the only way to close it is to click a cross with a mouse, the flow is incomplete.
Visible focus shows which element you are operating. This is a separate requirement: a reachable button with invisible focus can still create a barrier. Keyboard testing complements other accessibility checks; it does not replace them.
