This means: place it so that your arms are nearly at your side (elbow directly below shoulder) so that fewest muscles are used. This may mean that you must move the keyboard away from the "on yourlap" most comfortable position when you use the mouse or the trackball. Programable trackballs can make things easier but do take more setup. ron 1936, dz PD 1984 Ronald F. Vetter <[log in to unmask]> http://www1.ridgecrest.ca.us/~rfvetter/
