*'''Use the mouse''' to rotate the 3D figure: To really appreciate the three-dimensional nature of proteins and other molecules, you should drag the molecule to change the view. Imagine that when you drag, you are holding on to the atoms in the foreground, and dragging them while the center of rotation stays put. Try it! After rotating the molecules, can you see any features that were hidden before? Does it become easier to visualize the three-dimensional shape as you move the molecule? | *'''Use the mouse''' to rotate the 3D figure: To really appreciate the three-dimensional nature of proteins and other molecules, you should drag the molecule to change the view.

*'''Identify atoms''': Make sure the molecule is not spinning on its own (you can turn that off in the 3D browser by clicking the "± spin" text on the bottom). Then, hover (i.e. point with the mouse pointer without moving or clicking) over an atom, and a small pop-up text will appear. Try it! Here is an example text: "[ALA]23:A.CA #252" illustrating the format. It shows that the atom hovered over is part of alanine (ALA) residue number 23 of chain A (or subunit A). The atom is an alpha carbon (CA) and has the serial number 252 in the coordinate file. | *'''Identify atoms''': Make sure the molecule is not spinning on its own (you can turn that off in the 3D browser by clicking the "± spin" text on the bottom).

*'''Press shift''': When you press shift while dragging the molecule, the mouse pointer will look differently, and behave differently. Now, dragging up and down will zoom in or out, and dragging left and right will rotate the molecule around the z-axis. Try it! If your screen is touch-sensitive, you can also zoom with the usual two-finger pinch gestures. To move (translate) the molecule, press shift, double-click and drag. If your screen is touch-sensitve, you can also drag with two fingers. Try it! After you moved the molecule, it will still rotate around the old center of rotation (below we'll discuss how you can use the menu to change the center of rotation). | *'''Press shift''': When you press shift while dragging the molecule, the mouse pointer will look differently, and behave differently.
