Molecules can be freely translated, rotated and resized.
The most natural way to do it is using the mouse. The effect
will depend upon the tool currently selected. Tools are
located at the top of the display window. The selected tool
appear in inverse video, and the shape of the cursor is
affected by the current active tool.
translate, resize and rotate tools (rotate being active tool)
You can switch among these tools with "Tab" (or shift-Tab) key, providing the display window is currently active (i.e. the frontmost window).
When either the translate tool or the rotate tool are active, the translation or (rotation) can be constrained around the x, y, or z using key modifiers:
Note: if a little earth icon is shown below the first tool, the rotation takes place in absolute coordinates. Otherwise (little protein icon) molecules are rotated around their centrotid. Hence the first option allows you to rotate the molecule around any atom, providing that this atom has previously been centered (translated to the (0,0,0) coordinate). Refer to the tools section to know how to do that.
