COMMON KEY COMBINATIONS SX/DX
As we have already mentioned, in addition to their individual functions, some keys can be used in
combination with other keys to provide special functions. And, as in the case of the Alt and Ctrl keys,
some keys only function when pressed in combination with other keys. Before reading about some of the
more common key combinations, however, please remember one thing. As you start to use various
software packages you will quickly learn that each software has its own rules for the keyboard. Although
many of the keys, especially the typewriter keys and cursor movement keys, have these same functions in
most different software packages, some keys, especially the function keys F1 to F12, will often have
completely different functions. For [SX/DX 4-9] example, one software may use the F5 function key to
delete a block of text, and another software might use the F5 function key to insert a block of text.

The special key combinations that we explain here are those that are commonly used by MS-DOS, your
computer’s operating system software. Since MS-DOS loads every time you turn on your computer
before loading the particular applications software you wish to use, the better you know MS-DOS the
easier your computing operations will be. Also, some of these key combinations will take effect even
when you are using other applications software.

<Ctrl> <Alt> <Del> - The Warm Boot
To “boot up” your computer means to turn on your computer and load the operating system. When you
first turn on your computer each session by turning on your computer’s power switch, this is known as a
cold boot. Sometimes when you are using your computer, it will “hang”, which means that the display
will freeze and nothing you type on the keyboard seems to have any effect. This is a fairly uncommon
occurrence and is not a cause for panic. It can be due to any number of reasons such as a “bug” or defect
in the software package you are using. If this happens, you can turn off your computer for a few seconds
using the power switch. Then when you turn your computer on again, everything should be back to
normal.

This is rather inconvenient, however, and a far quicker way is by using the “warm boot”. All you have to
do is press and hold the <Ctrl>, <Alt> and <Del> keys and your computer will reboot without you
having to turn your computer on and off again.

Your computer will reboot whenever you press the <Ctrl> <Alt> <Del> keys no matter what software
you are using. In Windows, pressing <Ctrl> <Alt> <Del> will cause a message to pop up on the screen
with instructions on how to proceed. Because your system will reboot, make sure you only use it when
necessary as it erases the current contents of RAM. If you are editing a document and have not saved it
to floppy or hard disk, pressing <Ctrl> <Alt> <Del> will erase the document from memory and you will
have to start again. [SX/DX 4-10]

<Ctrl> S or <Ctrl> <Pause> - Pause Scrolling
Sometimes when you display data on your screen it will scroll off the screen faster than you can read it.
To pause the scrolling of data, you need to press <Ctrl> S or <Ctrl> <Pause>. When you are ready to
resume scrolling press <Ctrl> S or <Ctrl> <Pause> again.
