Click the icon to open the help topic for the selected command.

To learn about a command or subsystem, scroll down the command tree to locate the commands that interest you, such as the `:PROTocol` subsystem. Click on the expand button to view the available commands. You can also expand an entry by double clicking on the row. The previous figure shows the `:PROTocol:PROTocol:DFORmat` command. Notice that the drop-down list provides all of the available arguments for the command. You can make a selection, and click Run to execute the command. Click Query to display the current value in the Run/Query Output field. Some commands take an integer (int) or double (double) value.
