The Caps key on a keyboard is used to___________

Keyboards include several special-purpose keys that change how ordinary letter keys behave rather than typing a character themselves. The Caps Lock key is one of these.

Pressing Caps Lock toggles the keyboard between typing letters in upper case, capital letters, and typing them in lower case, small letters. Once activated, every letter key pressed produces a capital letter until Caps Lock is pressed again to switch back.

This is distinct from moving through pages, deleting files, or inserting spaces, which are handled by other dedicated keys such as Page Up or Page Down, the Delete key, and the Space bar respectively. Caps Lock's sole function is the upper case and lower case switch.

Exam takeaway: remember Caps Lock as a toggle switch for letter case, separate from navigation, deletion, or spacing functions on the keyboard.
