Abstract: Keyboard for choice of symbols having keys for the highly frequently used symbols divided in two groups, which has a position for placing the fingers except for the thumb for the left hand of the keys to the one group, and for the right hand on the keys of the other group. The groups are arranged at each side of the middle plane for an operator in such a way that the common plane of the key surfaces slope against the horizontal plane by their upwardly turned edges in against each other, and form an angle to the horizontal plane for each of the key planes, preferably about 30.degree. and at an angle to each other by their edges turned away from the operator. The keys in each group are divided in a number of vertically extending rows, having four keys in each row. At the upper side of the key plane, longitudinal supports have been arranged for the thumb of each hand along which support the thumb can slide.
