confused Keyboard overlay An overlay keyboard is a specialized Computer keyboardkeyboard with no pre set keys. Each key can be programmed with a wide range of different functions. Overlay keyboards are often used as a quick and easy way to input items with just two buttons. Overlay keyboards generally consist of a flat grid of unmarked buttons.

Advantages Overlay keyboards have several advantages over Computer keyboard conventional keyboards or Mouse computing mice . They do not require memorization of shortcut keys i.e. F5, Alt S, etc. nor do they require a great deal of fine motor control, making them ideal for people who have difficulty using a conventional keyboard. Overlay keyboards are easy to clean, and are much more resistant to spills or dust. The ability to change overlay sheets also makes it easy for a single overlay keyboard to have several different uses.

The PLUM keyboard is computer keyboard which varies from the traditional QWERTY keyboard in both physical key layout and letter arrangement. Unlike most keyboards, the PLUM keyboard organizes keys in a square grid, as opposed to the staggered rows of a typewriter. Though the Plum Keyboard is currently off line, it is still being promoted. Also, the purpose of the product is to teach non typists how to type and not to encourage Qwerty users to switch. The ergonomic advantages are secondary to the incredibly short learning curve. New typists learning Qwerty can typically expect a 4 to 6 week learning curve, whereas new typists learning Plum can touch type within two weeks. This is possible because Plum incoporates mnemonics to assist the learner. READONTHIS is not only easily remembered, they are the ten most frequently used keys and make up the home row where the fingers rest, thus minimizing finger movement. The Plum layout also gives equal time to each hand. With Qwerty, the left hand does 70 of the work, while the right hand does only 30 . It is notable that the Enter key has moved to a half length spacebar position alongside the spacebar itself. Each is now used by one thumb alone left for Enter and right for Space .

Unreferenced date December 2009 A keyboard buffer is a section of computer computer storage memory used to hold keystrokes before they are processed. Computer keyboardKeyboard buffers have long been used in command line interface command line processing. As a user enters a command, they see it Echo computing echoed on their computer display terminal and can edit it before it is processed by the computer. In time sharing systems, the location of the buffer depends on whether communications is full Duplex telecommunications duplex or half duplex. In full duplex systems, keystrokes are transmitted one by one. As the main computer receives each keystroke, it ordinarily appends the character which it represents to the end of the keyboard buffer. The exception is control character s, such as delete or backspace which correct typing mistakes by deleting the character at the end of the buffer. In half duplex systems, keystrokes are echoed locally on a computer terminal . The user can see the command line on his terminal and edit it before it is transmitted to the main computer. Thus the buffer is local. On some systems, by pressing too many keys at once, the keyboard buffer overflows and will emit a beep from the computer s internal speaker.
