<O Special MS-DOS Editing Keys
Many operating systems handle command input differently than
f00**) ms-dos does. One difference in particular that sets ms-dos apart is
its set of special editing keys. For instance, with ms-dos you don't
have to type the same sequences of keys repeatedly, because the
^-^ most recently typed command line is automatically placed in a
special storage area called a template.
By using the template and the special editing keys, you can take
(~*) advantage of the following ms-dos features:
■ You can repeat a command instantly by pressing two keys.
/"■s ■ If you make a mistake in a command line, you can edit and
retry it without having to retype the entire line.
■ With a minimum of typing, you can edit and execute a com-
/■—\ mand line that is similar to a previous one.
O How MS-DOS Uses the Template
When you type a command and press the return key, ms-dos
f0"*) automatically sends it to the command processor
(command.com) for execution. At the same time, ms-dos also
sends a copy of this command to the template. You can then
/-^ recall or modify the command by using the ms-dos special
editing keys.
