The caps lock is a key on a computer keyboard. Pressing it will set a keyboard mode in which typed letters are capitalized by default and in lower case when the shift key is pressed; the keyboard remains in this mode until caps lock is pressed again.
Cultural significance
The original utility of the key allowed the typing of all caps where appropriate, such as titles at the top of a page, without requiring the typist to manually keep the shift key depressed as long as needed. However, with the advent of modern styling such as small caps and section headers entered only once, this function has depreciated in usefulness.
On Internet chat systems and Usenet, typing in all capitals is considered rude, the large letters akin to shouting or yelling within the social context. On a more practical level, caps lock may be difficult to read. [1] A user who excessively uses capital letters may be advised to "lay off the caps lock."
Case sensitivity, a common security feature, can also conflict with caps lock. Many services and pages that utilize this feature warn the user up front to check the status of the caps lock function before entering a username and/or password. FAQ pages and other help guides also include this advice to reduce the incidence of complaints to support technicians for such a minor and easily-prevented issue. In Mac OS X, when caps lock is engaged at a login or authentication panel, a symbol for caps lock (⇪) warns of the state from within the password field.
In 2006, Pieter Hintjens began a campaign to remove the caps lock key from the standard keyboard layout. While the vast majority of manufacturers continue to produce keyboards which include a caps lock, some have removed it.[2] One Laptop Per Child computers, for example, do not have a Caps Lock key, replacing it with a "View Source" button.[3]
Shift lock
In QWERTY keyboards, though the caps lock mode capitalizes letters, it does not affect other keys, such as numbers or punctuation, in the way that the shift key does. A version of caps lock that affects all keys as shift does exists on certain layouts such as the French AZERTY and those of some older computers, including the Commodore 64; this function is called shift lock. The origin of the function is found on mechanical typewriters, where the shift key causes the type apparatus to physically shift to produce capitals and secondary characters. To lock this mechanism in place, a special non-character key could be depressed along with shift. The mechanism would not unlock until after pressing a shift key or shift lock again. Some operating systems and window managers allow caps lock to be used for a similar function.
