The left-handed keyboard Evoluent has the numeric field on the left side, so there is more space on the right side for using the mouse. The numeric field is in the way with the mice; fact. Evoluent has thought of something about this. The numeric field has been placed on the other side of the keyboard here. Because the numeric field is on the left side of the keyboard, the mouse can be moved closer to the body. Thus, you sit in a better ergonomic position and work more comfortably on top of that. The keyboard has some frequently used keys on the top, such as Page Up, Page Down, Home, as well as keys to adjust the volume or open the Internet browser.
