Write what to open a link in the same or new page?

When using a BUTTON, I can write the desired link or internal URL to where that button should take, but I have no idea about how to make the system opening that link/URL in the same page or in a new page.

I have attached a screenshot of the button's panel (in the left): how to set the desired target to be in the same or in a new page?

Thank you!

Hi
in the "target" option you can write "_blank"
this will open in a new page, if you leave it blank it will open in the same page

It worked fine, thank you!
