input with keypress

I want an input text box where users enter a certain word
if the word is entered correctly, a pop up appears or they are redirected to another page.
I don’t want to add a submit button, I want the even to trigger by pressing the Enter key.
(is there a way to stop the spell check from underlining the words red? the keywords aren’t always actual words)

this is me testing things, didn’t work:
$w . onReady ( function () {

let z = $w ( “#inputbox” ). value ;

$w ( “#inputbox” ). onKeyPress ( async ( event ) => {

**if**  ( event.key  ===  "Enter"  &&  z ===  "zex"  )  

{ $w ( ‘#button3’ ). hide ()}

});

nvm I figured it out

$w . onReady ( function () {

  $w ( "#inputbox" ). onKeyPress (( event ,  $w ) => { 

if ( event.key === “Enter” ) {
let z = $w ( “#inputbox” ). value ;

**if**  ( z ===  "zex"  )  

{ $w ( ‘#button3’ ). hide ()}

else

{ $w ( ‘#button3’ ). show ()}

}})});
