 ###What is the roundview() function?
 
-
 The Python script roundview.py includes the function `roundview()` that reformats the viewing port settings from seven rows to one row. The more compact format from roundview() is easy to copy and paste onto the command line. Other commands that are separated by semicolons can be added to the command line along with the settings. This defines a horiontal script. The script can include commnents that are isolated by semicolons. The horizontal script can be edited and tested repeatedly within PyMOL for many cycles without using an external text editor. This saves time during the development of a new molecular scene. The cursor can be moved around quickly on the command line with the readline commands:
 
 * **cntrl-a**  moves cursor to the beginning of the line
