In this spotlight, let’s look at interface components and navigation.
Users with visual or physical disabilities may use the keyboard to navigate and access content only using keys on the keyboard.
According to success criterion 2.1.2: No Keyboard Trap (Level A), keyboard-only users should be able to enter, interact and exit the content that receives focus using only the standard keyboard keys such as Shift and Tab, Tab, or the Arrow keys. A keyboard trap occurs when learners can navigate to an item, but then cannot move away from it. If the user needs to use non-standard keys to exit the content, then those instructions must be provided to the learner to avoid keyboard trap.
Because the way interactive elements work is determined by the authoring tool, it’s unusual to come across a keyboard trap in eLearning. However, it's always advisable to test your content with the authoring tool to ensure there are no traps.
It’s also possible to inadvertently create a trap for learners through certain design choices, such as a navigation button that disappears or a drag and drop activity that is required to be completed to move ahead in the training.
