EDITING
No one is perfect, and the Commodore 64 takes that into account. A
number of editing keys let you correct typing mistakes and move infor-
mation around on the screen.
There are two keys marked
Em'(CuRSoR), one with up and down
arrows 11.00:i"I:.~I,the other with left and right arrows r301:~:EI . You can
use these keys to move the cursor up and down or left and right. In the
unshifted mode, the,Em keys will let you move the cursor down and to
the right. Using the EmIiI key and ail keys allows the cursor to be
moved either up or to the left. The cursor keys have a special repeat
feature that keeps the cursor mQving until you release the key.
If you hit the .I/I I'A.I~. key, the cursor will move back a space, eras-
ing (DELeting) the previous character you typed. If you're in the middle
of a line, the character to the left is deleted and the characters to the
right automC?tically move together to cI.ose up the space.
A 'EDDed .1/h"I'A'I~. ,allows you to INSerT information on a line. For
example, if you noticed a typing mistake in the beginning of a line-
perhaps you left out part of a name-you could use the r301:io'l:EI:key to
move back to the error and then hit .1/h'1I'A'I~. to insert a space. Then
just Itype in the missing letter.
'IOI.:'A:lI],'positions the cursor at the "HOME" position of the screen,
which is:the' upper left-hand corner. A shifted IOI.:'A:I''''''''will clear the
screen and place the cursor in the home position.
.W"'..lmI8 operates as the name implies. It restores the computer to the
normal state it was in before you changed things with a program or
some command. A lot more will be said on this in later chapters.
