Tools Toolbar

    The toolbar consists of various command groups. The tools having exclusively chemical meaning are drawn in black, while tools for drawing graphical objects are in blue. For example, only one reaction arrow can be drawn on the canvas, but graphical arrows have no limit. These arrows look identical to the reaction arrow.
