Commodore Plus 4 - The Cursor Keys

-
The
Cursor
Keys
It's easy to move the cursor quickly around the screen in any direction.
Just press the cursor arrow key that points in the direction you want to
go. Like all keys on the Plus/4 keyboard, each cursor key can repeat
indefinitely while the key is held down. This automatic repeat function —
keeps the cursor moving until you release the key.
NOTE: You can move the cursor over letters and numbers on the
screen without affecting those characters.
INST/DEL —
You can INSERT and DELETE letters and numbers from the line —
you are typing by pressing this key. When you press this key by
itself, that character immediately to the left of the cursor disappears,
and the cursor moves over to where the missing character was. You
can use tne cursoi Keys to go : act- l \ the mid lie of a me in I thei use
DEL to DELete 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.
You can open up space to insert letters and numbers by using the
shift and inst keys. Space opens to the right of the cursor; —I
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.
The INST/DEL key saves a lot of time when you want to edit
or change what you've typed.
CLR/HOME
This key serves three functions: HOME, CLEAR, and CLEAR
WINDOWS. When you press this key, the cursor immediately moves to —
the top left corner of the screen. This is called the HOME position. The
rest of your screen stays the same. If you hold down the shift key _
and press CLR/home , no! only does the cursor move to HOME,
but the screen clears. All that remains on the screen is the blinking
cursor at the top left corner of the screen. If you press this key twice. —'
