Perl - start search by using search button or by pressing the enter key

Code:
#Build label and text box
$main->Label(
       -text => "Input string below:"
    )->pack();
 $main->Entry(
        -textvariable => \$text456
         )->pack();

$main->Button(
        -text => "Search",
        -command =>
            sub {
               errchk ($text456)
               }
    )->pack();


The snippet above setups a label, then a box to accept a text based user input. Then a Search button that calls a sub. The way it is written / shown, the search button works as it should. But the search does not execute if I enter text followed by pressing the enter key.

So, the question is, How do I give the user the option to either

input text, then press the enter/return key to begin the search
or
input text, then press the search button to begin the search ?


Thanks in advance !!

raise(n)						       Tk Built-In Commands							  raise(n)

__________________________________________________________________________________________________________________________________________________

NAME
raise - Change a window's position in the stacking order SYNOPSIS
raise window ?aboveThis? _________________________________________________________________ DESCRIPTION
If the aboveThis argument is omitted then the command raises window so that it is above all of its siblings in the stacking order (it will not be obscured by any siblings and will obscure any siblings that overlap it). If aboveThis is specified then it must be the path name of a window that is either a sibling of window or the descendant of a sibling of window. In this case the raise command will insert window into the stacking order just above aboveThis (or the ancestor of aboveThis that is a sibling of window); this could end up either raising or lowering window. EXAMPLE
Make a button appear to be in a sibling frame that was created after it. This is is often necessary when building GUIs in the style where you create your activity widgets first before laying them out on the display: button .b -text "Hi there!" pack [frame .f -background blue] pack [label .f.l1 -text "This is above"] pack .b -in .f pack [label .f.l2 -text "This is below"] raise .b SEE ALSO
lower(n) KEYWORDS
obscure, raise, stacking order Tk 3.3 raise(n)
