Numeric keypad
The numeric keypad is located to the right of the alphanumeric keypad. It provides a compact
numeric keypad with arithmetic operators + - x / and <Enter>. Use it to quickly type columns
of numbers and add up totals in the table cell in Excel, for example.
Key <NUM> (NumLock)
Instead of entering numbers, you can alternatively control the cursor and screen with the
keys of the numeric keypad (double assignment): By pressing the <Num> key you activate
and deactivate this cursor/screen control, see also "Status displays (Page 23)".
Function keys
Twelve programmable function keys are arranged in the topmost row of keys. The
arrangement of these keys depends on the software loaded.

You can use the standard functions labeled on the right side of each function key by pressing
and holding down the <Fn> control key beforehand, see section "Hotkeys (Page 21)".
