    This can be done with Term::ReadLine.

    Take a look at this wise reply of shmem: Re: Autocomplete in perl console application

    Update:

    Some sample code using another module, Term::Complete. Tested under Cygwin console.

    #!/usr/bin/perl -w
use strict;

use Term::Complete;

my %hash = (
    key1       => 'value1',
    key2       => 'value2',
    anotherkey => 'value3',
    fourthone  => 'value4',
);

my $user_input = Term::Complete::Complete('Try to input hash key: ', k
+eys %hash);

      Hello, I am having problems with cygwin using Term::Complete. Are there modifications required to module for it to work under cygwin? Seems to work fine under linux. Thanks,
