Buttons arrayed along the side of the main window control the generation of objects - rectangles, polygons, wires (fixed-width paths), arcs, and rounded objects. Other buttons enable setting related defaults, such as wire end style and width, and the number of vertices used in ``round'' objects. Additional buttons control operations such as erase/yank/put, xor, clipping, and rotating. In electrical mode, this menu changes to provide buttons for adding connection terminals, controlling the node-naming, and managing the simulation interface to the companion WRspice program. These buttons are described in chapter 7.
