1. A keyboard apparatus, comprising:

  • a mount;

    a plurality of control key means on the mount arranged in a single substantially unbroken V-shaped row;

    at least one control key means of the plurality of control key means having a base perimeter forming a chevron and lying wholly within said unbroken row and serving as a space bar;

    a plurality of alpha-numeric key means mounted on the mount arranged in a plurality of broken V-shaped rows, the plurality of alpha-numeric key means being arranged in a QWERTY configuration with said unbroken row to facilitate the entry of keyboard information;

    said plurality of alpha-numeric key means including a plurality of right QWERTY key means arranged in rows and staggered columns in a single common plane to facilitate their actuation in a rapid and accurate manner utilizing known and conventional QWERTY right hand digit keystrokes;

    each one of said plurality of right QWERTY key means being square in shape;

    said plurality of alpha-numeric key means further including a plurality of left QWERTY key means arranged in rows and staggered columns in said single common plane to facilitate their actuation in a rapid and accurate manner utilizing known and conventional QWERTY left hand digit keystrokes;

    each one of said plurality of left QWERTY key means being square in shape;

    means defining an irregularly shaped space disposed between said right QWERTY key means and said left QWERTY key means for completely separating them to help define said plurality of broken V-shaped rows;

    said space being further disposed substantially above said plurality of control key means for helping to define a narrow planar angle θ

    between said right QWERTY key means and said left QWERTY key means;

    said angle θ

    being sufficiently narrow to help cause the forearms of a user to assume a natural position in a non-parallel converging manner to cause the wrists of the user to be maintained in a substantially straight aligned position relative to the hands and forearms when the left hand and right hand digits are resting on the respective left and right QWERTY key means.
