As a result, default mappings are sometimes wrong (i.e., not matching the labels shown on the keyboard) when using a recent USB Apple keyboard on an older version of Mac OS X, which doesn't know about the new function key mapping of this keyboard (e.g., because Mission control and Launchpad didn't exist at that time, the corresponding labels ...
The TI-Nspire series uses a different operating system compared to Texas Instruments' other calculators. The TI-Nspire includes a file manager that lets users create and edit documents. As a result of being developed from PDA -esque devices, the TI-Nspire retains many of the same functional similarities to a computer.
The Gold Key is used to invoke single-key functions which may be located on either the main keyboard or the numeric keypad. For example, on the WPS-8 word processing system, the main keyboard key C is marked "CENTR", in gold lettering, on its front surface; the keystrokes GOLD C invoke that word processing function to center the current line of text.
These keys can be selected using the mouse or another pointing device, or a single key or small group of keys can be used to cycle through the keys on the screen. The on-screen keyboard is the most common type of virtual keyboard. The accuracy of this keyboard depends only on hitting the right key.
In present-day applications, group keys are commonly used in conditional access systems, where the key is the common key used to decrypt the broadcast signal, and the group in question is the group of all paying subscribers. In this case, the group key is typically distributed to the subscribers' receivers using a combination of a physically ...
The IBM 3270 is a family of block oriented [1] display and printer computer terminals introduced by IBM in 1971 [2] and normally used to communicate with IBM mainframes. The 3270 was the successor to the IBM 2260 display terminal. [3] Due to the text color on the original models, these terminals are informally known as green screen terminals.
Example of a Key Derivation Function chain as used in the Signal Protocol.The output of one KDF function is the input to the next KDF function in the chain. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a ...
A typical 105-key computer keyboard, consisting of sections with different types of keys. A computer keyboard consists of alphanumeric or character keys for typing, modifier keys for altering the functions of other keys, [1] navigation keys for moving the text cursor on the screen, function keys and system command keys—such as Esc and Break—for special actions, and often a numeric keypad ...
