Editing Practical Pymol for Beginners (section)

===About the command line===
The PyMOL command line is a great tool that lets the experienced user change all sorts of options that simply don't appear in the point-and-click graphical interface. It can also be a lot faster. Combined with scripting, it is a powerful option for automating tasks and making intricate sets of changes. But, it's complex, and page upon page of PyMOL documentation cover these commands, so we're going to ignore them as much as possible.

Although this guide may include some text commands and links to more advanced documentation, they're purely optional and meant to be informative. 

To run any text command, type it in at a '''PyMOL>''' command line and hit ''[Enter]''.
