Hello fellow monks,

I'm following Curses::UI::Tutorial on CPAN with the following code: 

#!/usr/bin/env perl

use strict;
use Curses::UI;

my $cui = new Curses::UI( -color_support => 1 );

my @menus = (
    { 
        -label => 'File',
        -submenu => [
            { -label => 'Exit', -value => \&exit_dialog }
        ]
    }
);

sub exit_dialog {
    my $ret = $cui->dialog(
        -message => "Quit?",
        -title => "Quit",
        -buttons => [ 'yes', 'no' ]
    );
    exit(0) if $ret;
}

my $menu = $cui->add(
    'menu', 'Menubar',
    -menu => \@menus,
);

my $win1 = $cui->add(
    'win1', 'Window',
    -border => 0,
    -y => 1
);

my $texteditor = $win1->add(
    'text', 'TextEditor',
    -text => "Line1\n"."Line2\n"
);

$cui->set_binding(sub { $menu->focus() }, "\cx");
$cui->set_binding( \&exit_dialog, "\cq");

$texteditor->focus();
$cui->mainloop();

The menubar will loose its focus when it receives an escape keystroke. When I run the program, it takes a full second to respond. According to ncurses(3), the default delay for escape keystroke is 1000ms and could be changed by ESCDELAY variable or c function set_escdelay(3X). However, I didn't see any method/function corresponding to set_escdelay in the CPAN documentation.

Is there any method, other than to change ESCDELAY, to change the escape keystroke delay?

Feel free to correct any of my mistakes. Thanks in advance.
