You refer to the letter "N" when you talk about some of the key sequences, but there is no N key on my keypad.

[ModeratorRA]

"N" is a general term that represents a user-supplied number in a key sequence. Whenever you see N listed as part of a key sequence--for example, 14.NNE--replace the N(s) with actual numbers (e.g., 14.32E).
