To clarify the difference between these two functions, here’s a short comparison:
 If you use the Learn by Key Label function, and define only one key command for the
key, it will be used, no matter which of the two keys (either number 7 key, for
example) is pressed.
 If you use the Learn by Key Position function, and define two key commands (one for
the alphanumeric keyboard, one for the numeric keypad), then the appropriate key
command will be used (one for each number 7 key, for example).
Using Existing Key Commands
In circumstances where an existing local key command combination is used, when
assigning a new global key command, the following warning message will appear:
You have three options: Cancel, Replace, or OK.
 Cancel: Does not alter existing assignments.
 Replace: Replaces the existing shortcut (assigned to the chosen key command
combination) with the selected function.
 OK: Assigns the key command combination to the selected function, while retaining
the existing key command or function.
To delete key assignments:
1 Select the function with a key assignment that you’d like to delete.
2 Activate the Learn by Key Label or Learn by Key Position button.
3 Press Backspace.
4 To erase more assignments, repeat the first and third steps.
5 Deactivate the Learn by Key Label or Learn by Key Position button.
