2.2.3 Shifted Functions
A number of the keys in the numeric keypad have an additional use when preceded by the
[SHIFT] key (see Figure 2-4). These additional uses are labeled in blue. When the [SHIFT] key
is pressed, the LED to its left lights and remains on until a function key is pressed (the shift key
and the function key should not be held down at the same time).
The following shifted functions are available (each heading is followed by the numeric key
which performs the shifted function):
