ABSTRACT:
A keyboard having an improved numeric section and an improved numeric key cluster in the numeric section. The keyboard preferably includes an alphanumeric or QWERTY section and an editing section laterally disposed from the numeric section. A row of function keys is preferably provided above at least the numeric key cluster. The present invention also provides keys frequently used with the numeric section within, or in close proximity to, the key cluster in the numeric section. A Tab key or an Equals “=” key has been provided within the key cluster for improved efficiency. Additionally, a row, preferably including four keys, is provided above and in close proximity to the numeric key cluster. These keys preferably include a Left Parenthesis “(“ key, a Right Parenthesis “)” key, a Backspace key, and a Tab key or an Equals “=” key, whichever is not provided within the numeric key cluster. The keyboard does not include a specifically labeled NumLock key within the numeric key cluster. The keys provided in the numeric key cluster and in its proximity are frequently used with digit keys and enhances the effectiveness of the numeric key cluster when it is being used for many program applications and alleviates the problem of having to reach over number pad or use the other hard to acquire keys in the alphanumeric section of the keyboard.
