Numeric Keypad
The numeric keypad consists of the digit keys (0 through 9), a decimal
point key, and a backspace key, The backspace key has dual
functions for both backspacing and for changing the sign of a value to
positive or negative. Use these keys at any time when the active
function requires a value input. The backspace key function changes
with the situation.
If you are modifying a previously entered value:
• If the value is negative, pressing the backspace key deletes the
entire value and leaves the negative sign. Subsequent key presses
change the sign between positive and negative states.
• If the value is positive, pressing the backspace key deletes the entire
value and also changes the sign to a negative state. Subsequent key
presses change the sign between positive and negative states.
If you are entering a new value:
• If the cursor is to the right of the digits, pressing the backspace key
deletes the digit immediately to the left. When no digits remain,
subsequent key presses change the sign between positive and
negative states.
• If the cursor is on a digit, pressing the backspace key deletes the
digit immediately to the left. When a single digit remains, pressing
the backspace key changes the negative sign (if present) to positive
and then subsequent key presses have no effect.
These keys have autorepeat capability (except for the decimal point
key). Hold a key down and its function is continuously executed until
you release it.
