Here are a few keyboard shortcuts you can use to perform common tasks
      quickly. Many more are available in addition to what is listed here. For
      more command line and keyboard shortcuts, visit:
[Ctrl] + [Alt] +
	  [Backspace] = kills your current X session. Kills your
	  graphical desktop session and returns you to the login screen. Use
	  this if the normal exit procedure does not work.
	
[Ctrl] + [Alt] +
	  [Delete] = shutdown and reboots your Red Hat Linux
	  system. Shuts down your current session and reboots the OS. Use only
	  when the normal shutdown procedure does not work.
	
[Ctrl] + [Alt] + [Fn]
	  = switches screens. [Ctrl]+[Alt] + one
	  of the function keys displays an available screen.  By default,
	  [F1] through [F6] are shell prompt
	  screens and [F7] is the graphical desktop screen.
	
[Alt] + [Tab] = switches tasks in a
	  graphical desktop environment. If you have more than one application
	  open at a time, you can use [Alt] +
	  [Tab] to switch among open tasks and applications.
	
[Ctrl] + [a] = moves cursor to the
	  beginning of a line. This works in most text editors and in the URL
	  field in Mozilla.
	
[Ctrl] + [d] = logout of (and close)
	  shell prompt. Use this quick shortcut instead of typing
	  exit or logout.
	
[Ctrl] + [e] = moves cursor
	  to end of a line. This works in most text editors and in the URL field in
	  Mozilla.
	
[Ctrl] + [l] = clears the
	  terminal. This shortcut does the same thing as typing
	  clear at a command line.
	
[Ctrl] + [u] = clears the current
	  line. If you are working in a terminal, use this shortcut to clear the
	  current line from the cursor all the way to the beginning of the line.
	
[Middle Mouse Button] = pastes highlighted
	  text. Use the left mouse button to highlight the text. Point the
	  cursor to the spot where you want it pasted. Click the middle mouse
	  button to paste it. In a two mouse system, if you configured your
	  mouse to emulate a third mouse button, you can click both the left and
	  right mouse buttons simultaneously to perform a paste.
	
[Tab] = command autocomplete. Use this command when
	  using a shell prompt. Type the first few characters of a command or
	  filename and then press the [Tab] key. It will
	  automatically complete the command or show all commands that match
	  the characters you typed.
	
[Up] and [Down] Arrow = shows command
	  history. When using a shell prompt, press the [up] or
	  [down] arrow to scroll through a history of commands
	  you have typed from the current directory. When you see the command
	  you want to use, press [Enter].
	
clear = clears the shell prompt screen. Type
	  this command to clear all visible data from the shell prompt screen.
	
exit = logout. Type this at a shell prompt
	  to logout of the current user or root account.
	
history = shows history of commands. Type
	  this at a shell prompt to see a numbered list of the previous 1000
	  commands you typed. To display a shorter list of previously used
	  commands, type history followed by a space and
	  a number. For example, history 20.
	
reset = refreshes the shell prompt
	  screen. Type this at a shell prompt to refresh the screen if
	  characters are unclear or appear corrupt.
