Key



See: Rabbit brand

A key is a metal instrument used to open a lock. A typical key consists of two parts: the blade, which slides into the keyway of the lock and distinguishes between different keys, and the bow, which is left protruding so that torque can be applied by the user. The blade is usually designed to open one specific lock, although master keys are designed to open sets of similar locks.

DOSKey


DOSKey is a utility for MS-DOS and Microsoft Windows that adds command history, macro functionality, and improved editing features to the command line interpreters COMMAND.COM and cmd.exe. It was included as a TSR program with MS-DOS and PC-DOS versions 5 and later, and with Microsoft's Windows 95/98/Me.

In current Windows NT-based operating systems DOSKey's functionality is built into cmd.exe, although the DOSKey command is still used to change its operation.

The absence of a command history in COMMAND.COM was a serious inconvenience from the earliest versions of MS-DOS. Numerous third-party programs have been written to address the issue; many were available long before Microsoft supplied DOSKey. Some of these also provide additional editing capabilities lacking in DOSKey, such as filename completion. Some of the better-known DOSKey alternatives are Chris Dunford's ced, Sverre Huseby's dosed, Ashok Nadkarni's cmdedit, Steven Calwas's Anarkey, Eric Tauck's Toddy, and Paul Houle's enhanced DOSKey.

From Wikipedia, the free encyclopedia

The piano, a common keyboard instrument

A keyboard instrument is any musical instrument played using a musical keyboard. The most common of these is the piano. Other widely used keyboard instruments include various types of organs as well as other mechanical, electromechanical and electronic instruments. In common language, it is mostly used to refer to keyboard-style synthesizers.

Among the earliest keyboard instruments are the pipe organ, hurdy gurdy, clavichord, and harpsichord. The organ is doubtless the oldest of these, appearing in the 3rd century BC, although this early instrument--called hydraulis--did not use a keyboard in the modern sense. From its invention until the 14th century, the organ remained the only keyboard instrument. Often, the organ did not feature a keyboard at all, rather buttons or large levers which were operated by a whole hand. Almost every keyboard until the 15th century had 7 naturals to each octave.

Yale Lock

AT A GLANCE:
Yale's lock used a flat key with serrated edges like the ones we still use today. When inserted into the lock, the key pushes the bottom pins into the right position, which allows the user to turn the key and unlock the lock. The cylinder lock perfected by Yale is based on a mechanism first employed by the ancient Egyptians over 4000 years ago.
