KSH command completions.
I want to do the Auto command completion in ksh for my product's CLI. For that I am using the key binding mechanism. But am stuck at following points.

1. I am not able to use .sh.edtext variable while KEYBD trap. As I know this variable contains Characters in the input buffer during a KEYBD trap. But in my script, this variable is always NULL. Can you please tell me How can I get the content of input buffer in my script.
2. If somehow I get the input buffer in my script then I have to compute the next possible completions based on the input buffer. Now:
A. If there is only completion.
In this case I have to append this to input buffer and put this new string on command prompt. How can I replace the content of command prompt with new string?
B. If there are more than 1 possible completion:-
I have to show all completions below the command prompt. This I can do with print command. Is there any other ways to do this.

I am using the following script for key bind:-
-------------------------------
typeset -A Keytable
trap 'eval "${Keytable[${.sh.edchar}]}" && VX_COMMAND=${.sh.edtext}' KEYBD
function keybind # key [action]
{
typeset key=$(print -f "%q" "$2")
case $# in
2) Keytable[$1]="$key"
;;
1) unset Keytable[$1]
;;
*) print -u2 "Usage: $0 key [action]"
return 2 # usage errors return 2 by default
;;
esac
}

export VX_COMMAND
keybind $'\Ew' function.sh #I want to bind Alt+w with function.sh and want to use input buffer in function.sh.
---------------------------------------

I didn't found these answers with GOOGLE.

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
           able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
           performed.
