Every time you press a key on your computer keyboard, the corresponding key on the virtual keyboard will light up and remain highlighted. Test each key to ensure they are all working correctly. If the entire keyboard is highlighted (or at least the keys available on your physical keyboard), then – HURRAY! – your keyboard has passed the test! ⚠️ due to Scratch's limited keyboard functionality, not every displayed Key is possible to Test. At least letters and numbers should work ⚠️ What keyboard layout is this test designed for? The design of the on-screen keyboard is based on a typical English or American keyboard layout (BS 4822), but it is not an exact copy. The test should work with any keyboard layout, though the keys on your physical keyboard may be arranged differently. Whether the physical keys are in the same position or not, the on-screen keys will light up when pressed.
