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

[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] = From a non-graphical shell prompt, shuts down your Red Hat Enterprise Linux system. Use only when the normal shutdown
procedure does not work. In a graphical desktop session, this shortcut
displays the desktop logout screen that allows you to logout, reboot,
or shut down your system.
[Ctrl] + [Alt] + [Fn]
= switches screens. [Ctrl]+[Alt] + one
of the function keys displays an available screen. By default,
[F1] through [F6] are text-mode 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 system with a two-button mouse, 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].
