Editing An Object In The Command Line - HP 48G Series Quick Start Manual

Editing an Object in the Command Line
Making typing errors while creating numbers and other objects is a
common problem, but one that is easily fixed. After all, the command
line is designed to be a preliminary work area where you can create,
edit, or refine an object before you decide to enter it, thus declaring it
"ready."
As long as you see the command line, you can edit whatever you're in
the process of creating. Here's a list of the editing keys and what they
do:
Erases the entire Command Line, causing it to disappear
until you start typing again.
Moves the cursor (#) to the left.
Moves the cursor to the right.
Moves the cursor to the line above (for objects requiring
more than one line).
Moves the cursor to the line below (for objects requiring
more than one line).
Erases the character to the left of the cursor.
DEL Erases the character underneath the blinking cursor.
Each of these keys are editing keys only while you are using the
command line. At other times, each key performs the action printed
above it. When there's no command line, («) becomes (DROP),
becomes (CLEAR) and so forth. This allows you quicker access to these
operations (you need not press the @ shift key first).
