The "Edit/Drag atoms" menu item or button allows the atoms in the molecule's image to be moved using the mouse. When dragging an atom one can move it in the Z direction (in parallel with the view) using the keys Num2/Num8 (while the left mouse button is pressed). The buttons , , switch between "drag atoms", "drag fragments" and "drag molecules" modes, the latter two modes allow one to drag and rotate groups of several atoms (for details, see Constructing molecules). When a group of atoms is dragged, the buttons Num1-Num9 rotate it or move it in the Z direction.
