Where's the recent apps menu?

[you]

Sorry if I'm being naive, but how do you open the Recent Apps menu (the menu that shows you all of the apps that are open)? It looks like this in Android Lollipop (can't find one of Jelly Bean): http://img.wonderhowto.com/img/49/72/63550209324803/0/install-android-lollipop-recent-apps-menu-any-android.w654.jpg  I see a home, menu, and back button, but that's about all. I know that the home button brings you to the home screen, the back button, well, goes back, and the menu button would presumably open the Recent Apps, but it just opens the menu of the current app. Any help? Again, the answer is probably really simple, but I literally just installed YouWave and I have no idea about what I am doing.

Nevermind, the navigation bar was not visible in the resolution that I was running at, but I changed it to a larger one and it now is. Thanks for taking your time to click on this article!
