The Caps Lock on a keyboard has a special position. This is because it is rarely used for key combinations; rather, its use changes the input permanently. This is why keyboards for Mac or PC as well as on notebooks such as the Apple MacBook are also equipped with an LED that indicates that the Caps Lock key is active. In English the button is called Caps Lockbecause it locks in capital letters (Caps). There is also a corresponding switch on typewriters, the Shift lock or Shift lock is called. It causes the permanent use of the shift key or shift function.
The history of these special keys goes back to the use of typewriters. Because almost every typewriter has a switch lock, thanks to which either the platen is raised or the type carriage is lowered and locked in place. In contrast to the shift key, which must be held down to use the second assignment of the keys (capital letters and special characters), the caps lock key is only pressed once and then enables permanent writing in capital letters. This can be useful on typewritten documents for a heading, name in a document, or the like.
The difference between toggle lock and caps lock
From a purely technical point of view, there is a difference between the “Shift Lock” with the symbol ⇩ and the “Caps Lock” with the symbol on the computer keyboard of Mac and PC. Here is a short form of the respective explanation so that nobody gets confused:
Shift lock ⇩: Simulates the permanent pressing of the shift key so that the second assignment is activated on all keys (letters, numbers, characters)
Caps Lock Key: Simulates only holding down the Shift key for letters, so that only capital letters can be written, but numbers can also be written
