The standard keyboard with ergonomically-arranged keys has all cursor and display movement keys positioned between the left and right halves of the keyboard (2,3), namely four arrow keys (10), insert (11), remove (12), position (13), end (14), page-up (15) and page-down (16). Also left and right special keys (7,8), and between F6 and F7 there is a 'Scroll' key (20). The space bar is split into a left (17) and right (18) sections. A mouse function (5) is also incorporated. The cursor may be driven at increased or double speed if both left and right space bar keys (17,18) are pressed.
