When you read this Guide, you will see that certain words are represented in different fonts, typefaces, sizes and weights. This highlighting is systematic; different words are represented in the same style to indicate their inclusion in a specific category. The types of words that are represented this way include the following:
[key]
A key on the keyboard is represented like this. For example: Press [Enter]. A combination of keystrokes is designated as follows: [key]-[key].
command
Linux commands and code examples are represented this way. This style should indicate to you that you could type in the word or phrase on the command line and press [Enter] to invoke the command.
filename
Filenames, directory names, paths, RPM package names, network requisites, and actual parameters settings are represented this way.
Heading
The headings of dialog boxes, names of menu items, and interface elements in Graphical User Interface (GUI)
