udfk - description file for form user-defined function keys
mio -u file
export UDFK=file
...
do_form("formname", NULL)
Predefined character sequences constitute mio's function key set. This same set of sequences is used by do_form(3c). These sequences can be changed by listing their replacements in the udfk file, and passing the udfk file name to mio in the -u option, or setting the UDFK environment variable for do_form(3c).
The format of the udfk file is described and demonstrated below. Blank lines and lines beginning with an asterisk in column one are comments, and are ignored. All other lines consist of two white space separated sequences, optionally followed by a comment. The first sequence or string should be a special keyword describing the command key. The keywords are listed below. The second sequence should consist of a string containing the new character sequence for the command key. Unprintable characters may be represented using an escape sequence. The escape sequence consists of a backslash followed by exactly two hexadecimal digits.
The table below lists the keyword names and their default values. It is in proper description file format.

When the description file contains only a partial list of keywords, keywords not appearing in the file keep their previous values.
mio and do_form() perform the first command that matches the user input. Hence, when the character sequence for one command is a leading substring of the sequence for another command, the latter is never performed.
