Using Different Terminals 

If the terminal that you're using is not a 239x, 262x or 264x terminal or
if you're using a non-English keyboard, you must define the characters
that represent the command keys.  Enter one character for each command
key into the first 24 characters of the first record in the file CMDKEYS.
Enter the ASCII representation of the key(s) on the keyboard.  You can
create or modify CMDKEYS using any text editor, such as EDITOR.
