Symmetrical design computer keyboard including cursor control key - has number and special-command keys to left and clear of middle portion

摘要

The computer keyboard has keys in several rows, those for numbers and special commands like "return" or "enter" being clear of the middle part. These keys are clear of the middle part and to the left of it so they can be operated with the left hand during normal use. Alternatively the number of keys are to the left or right, as can the special command keys.
