I have a friend who says that when he hits the default tower menu key (T) he can hit it twice and pull up a second tower menu. He says he can get the tower to give him (or reset) the altimeters.

I cannot get this second tower menu screen. When I hit the tower key a second time it deletes the menu from my screen.

Is there some kind of config setting or other means to enable this second menu

I just discovered that it depends on which keystroke file you are using

As in, don't use a keyfile from a previous version of Falcon, like the developers told people not to do multiple times.
