The keyboard keys like Caps lock that turn on features on or off are called

The correct answer is D, Toggle Keys. A toggle key switches a feature on with one press and off with the next, so it has two states and keeps whichever one you left it in. Caps Lock, Num Lock, Scroll Lock and the Insert key work this way, and most keyboards carry a small indicator light that glows while the feature is on. Caps Lock, for instance, holds capital letters until it is pressed a second time. Option A is wrong because navigation keys move the cursor or the view: the four arrow keys with Home, End, Page Up and Page Down. Option B is not a standard class; keys such as Enter, Esc, Tab and the Windows key are grouped as control or special keys, and none of them stay switched on. Option C is wrong because the function keys are F1 to F12, which run one command each time they are pressed. Exam tip: the four toggle keys are Caps Lock, Num Lock, Scroll Lock and Insert.
