About Caps Lock Key

On most computer keyboard layouts, this key is located on the left side of the keyboard, below the tab key and above the shift key, though it appears in other locations on some keyboards.

The function of the caps lock key is to toggle an option on or off that makes every typed letter appear by default as a capital letter instead of a lowercase letter.

In daily work, the caps lock key is utilized often when the user needs to type a long string of capital letters, for instance, an acronym that contains several letters.

Typically, it is easier to use this key only when there needs to be a large number of capital letters. Otherwise, it is simpler to hold down the shift key to achieve one or two capital letters in a row.

When the caps lock toggle is turned on and the default typing mode uses all capital letters, the shift key can also be held down to temporarily switch back to lowercase. This function is similar to how shift is used to create capital letters when caps lock mode is turned off. This may be a useful option when typing mostly long strings of capital letters with the occasional lowercase letter.

The caps lock key is not generally considered a vital key on the keyboard.

Some computer users choose to use a program to disable the caps lock function, often to avoid frustration from accidentally hitting the key while typing and discovering that all of the text is suddenly in capital letters.
