b
symbol is on the screen, you can use the
d
key to move the cursor to the
left and scroll the screen.
• Scrolling to the left causes part of the expression to run off the right side of the display,
which is indicated by the
\
symbol on the right. While the
\
symbol is on the screen,
you can use the
e
key to move the cursor to the right and scroll the screen.
• You can also press
f
to jump to the beginning of the expression, or
c
to jump to the
end.

Number of Input Characters (Bytes)
As you input a mathematical expression, it is stored in memory called an “input area,”
which has a capacity of 99 bytes. This means you can input up to 99 bytes for a single
mathematical expression.
Normally, the cursor that indicates the current input location on the display is either a
flashing vertical bar (
|
) or horizontal bar (
). When the remaining capacity of the input area
is 10 bytes or less, the cursor changes to a flashing box (
k
).
If this happens, stop input of the current expression at some suitable location and calculate
its result.

Insert Mode and Overwrite Mode
The calculator has two input modes. The insert mode inserts your input at the cursor
location, shifting anything to the right of the cursor to make room. The overwrite mode
replaces the key operation at the cursor location with your input.
