Chime Viewer Basics A "live" molecule can be displayed in different molecular models by right-clicking on the molecule and changing the display mode to one of the following: a) wireframe; b) stick; c) ball and stick; and d) spacefill. "Ball and stick" and "spacefill" closely resemble the conventional physical molecule model set. A molecule can also be rotated and resized. These are done by the mouse and keyboard combinations. Hold these keys down while you click-and-drag with the mouse button, to produce the indicated Result in the image (e.g. Ctrl-Right means hold down the Ctrl key while clicking the right mouse button in Windows). Test-drive the following molecule: Macintosh Windows Result     None Left Rotate about X or Y axes Command Ctrl-Right Translate in X or Y direction Shift-Command Shift-Right Rotate about Z axis Shift Shift-Left Zoom in or out Control Ctrl-Left Slab in and out (Applies if Slab Mode has been selected in the Options Menu.)
