You can rotate, translate, and zoom your molecule using the mouse.
You need to drag with the mouse: press a mouse button, and while holding it down move it. Which mouse button, and which modifier key you press at the same time, determines what will happen:
| Rotate | Left |
| Rotate in-plane | Ctrl-Left |
| Translate | Middle, or Alt-Left |
| Zoom | Right, or Command-Left (drag up or down) |
The rotate, translate, and zoom operations change how you look at the molecule, they do not change the coordinates.
Click once somewhere in empty space to make sure nothing is selected. Click with the left mouse button, and drag: your molecule will rotate. Click with the left mouse button with the ctrl-key, and drag: your molecule will rotate in-plane. Click with the middle mouse button (or left with alt-key), and drag: your molecule will be translated. Click with the right mouse button (or left with command key), and drag up and down: you will zoom closer to or away from your molecule. Using all these options, try to position the ethanol as closely as possible as in the following image:
