User Interfaces
Keyboards often include a small LED to indicate that caps lock is active—either on the key itself, or in a row with scroll lock and num lock indicators. However, some new laptop and wireless desktop keyboards lack the LED, instead providing software that gives an on-screen indicator.
People typing case-sensitive passwords that are not displayed verbatim on the screen may not realize that caps lock is on, causing errors. Help guides, tech support materials, and sometimes the interface itself may include advice on checking caps lock before typing a password. In Windows login screens, a warning that caps lock is on is shown in a balloon near the field. In Mac OS X, when caps lock is on, a caps lock symbol (⇪) is displayed inside a password field. Operating systems may also provide audible notifications when caps-lock, num-lock, or scroll-lock buttons are toggled.
Some manufacturers include an option in the controller software to deactivate the caps lock key. This behaviour allows users to decide themselves whether they want to use the key, or to disable it to prevent accidental activation.

Famous quotes containing the word user:
“A worker may be the hammer’s master, but the hammer still prevails. A tool knows exactly how it is meant to be handled, while the user of the tool can only have an approximate idea.”
—Milan Kundera (b. 1929)
