I want the new page doesnt appear on the menu

Hi Blueowl this is an easy question.. I have just created a new page but in this case i dont want it appears on the menu of my website. What I need is this page is seen thanks to a button on other page.

The thing is that I have seen in control panel in “MENUS” the new page is not there. But if you go to my website it is there..
