ABSTRACT:
In an apparatus for handling objects such as documents and tools a menu of options (30) is displayed, which options (31a . . . 31h) are placed in a curved band (31) around the position of the cursor at the moment of activating the menu. The shape of the curved band is optimized for the movement of a hand-held pointer device, such as a stylus, and allows easy movement of the pointer device along the options. The band (31) may follow part of the circumference of a circle of which circle inner portions (32, 33) may be used for the display of several sets of sub-options.
