That shouldn’t be a big problem…
Your wished function → is just a simple → REDIRECTION to another page/site?
<buttononclick="window.location = 'http://weather.com';">Go</button>
…then you will need this one —> to - Velo API Reference - Wix.com
But the proble in Wix-environment will be, that you are not able to control keyboard on the whole page/site.
Instead you only get KEYBOARD-CONTROL on single elements! I know → BAD (but perhaps one day, we will get this feature! BTW: Anybody already putted this onto the WISHLIST → it’s CHRISTMAS soon!) !!!
So i am not sure, if your wished function is doable → pehaps using a custom element?
But an element is an element and not the page itself!
Conclusion:
A missed function on the wix-plattform!
