The cursor, the flashing block that marks where you are on the
computer screen, can be moved quickly and easily around the screen
by using the CURSOR KEYS. There are four separate cursor keys,
each
with an arrow pointing out the direction the key moves the cursor -
up, down, ;eft. or right. You can use the cursor keys to move the
cursor over anything on the screen without affecting those Characters
Like all keys on the Commodore 16 keyboard, each cursor key can
automatically repeat. Th;s means that if you Continually hold the key
down, the cursor continuously moves in the direction of the key
you're
pressing (saving you from having to perform the tabled "rapid-fire key-
press").
INSTOMIL
You can INSERT and DELETE letters and numbers from the line you are
typing with this key. When you press
this key oy itself, the typed
character immediately to the left of the cursor disappears. and the
cursor moves over to wnere the missing character was. You can use
the cursor keys to go back to the middle of a line and then use DEL to
erase a letter. When you do this, the letter to the left is deleted, and the
rest of the
letters
on the line move over one space to the left to close
the gap.
To open up space to insert letters and numbers, type this key along
with SENT Space opens to the right of the cursor: the cursor
itself
does not move. When you insert space in the middle of a line of letters.
the rest of the line moves to the right

what you've typed

press this key alone, the cursor immediately moves to the top left
corner of the screen (which Is known as the HOME position). The rest
of your screen stays the same If you hold down the
r

press ammo= . not only does the cursor move to HOME, but
everything on the screen is erased (or cleared). All that remains on the
