The following sections provide a complete description of the functions of the command-line editor with short examples depicting how each editing key works.
Throughout the examples the underline character, "_", will be used to represent the current cursor position. In addition, "OA" is used to represent the Open Apple key and the term word is used to indicate a string of characters consisting of only letters, digits, and underscores. To the right of a editing key entry is the bindkey function name which is used to remap editing functions to new keys. This information is included for reference purposes only. See the Chapter called Builtin Command Reference for more information on the bindkey command.
It should be pointed out that at this stage that the user should not be concerned with what the actual commands used in the examples do, rather the user should concentrate on how the command-line editor functions work.
