.The following table lists all of the keys that can be redefined. The table lists the key's full name, its two-character name (called the "key code"), and the corresponding key used on an MS-DOS and Windows keyboards. The key code is used in the terminal database file on UNIX and VMS systems to identify the corresponding key-sequence. For more information about user-defined keys, see Appendix M under Keyboard Differences.

Control keys (Control plus another key) are not defined in the terminal database file. They are directly mapped by the runtime system to the corresponding control-key ASCII value. They can be referred to by either their ASCII value or by the key code listed. The DEL key does not have a key code; it can be referred to only by its ASCII value (127).
Some keys may have more than one name. When this occurs, the names have the following precedence:
1. Host name
2. Terminal database file name
3. Control-key name (if applicable)
For example, if a terminal whose left arrow key produces a Control-H is being used, and Control-H is the system's backspace key, that key would be treated as a Host's Backspace key (ZB). If the host's backspace were redefined (by operating system command) to be some other key, then this key would be considered a Left Arrow key (kl). It would be considered a Control-H (^H) only if the terminal database file were edited and the "kl" definition changed or removed.
