to make the cursor jump to the beginning of the expression or 
to jump to the end of the expression.
Input Expression and Calculation Result "More" Indicator (
, 
)
If you see a pointer ( or ) symbol on the right side of either an input expression line or calculation result line, it means the displayed line continues to the right. Use 
and 
to scroll the line left and right.
When you see at the right end of a calculation result line, you can jump to the end of the result by pressing . To jump to the beginning of a calculation result line, press .

Parentheses Auto Complete
If you execute a calculation that includes both division and multiplication operations in which a multiplication sign has been omitted, parentheses will be inserted automatically as shown in the examples below.
- When a multiplication sign is omitted immediately before an open parenthesis or after a closing parenthesis.
Example: 6 ÷ 2(1 + 2) → 6 ÷ (2(1 + 2))
- When a multiplication sign is omitted immediately before a variable, a constant, etc.
Example: 6 ÷ 2π → 6 ÷ (2π)
Input Limit Indication
The cursor will change shape to 
when there are 10 bytes or less of allowed input remaining. If this happens, end calculation input and then press .
