Snorkel questions

Thanks.

My submarine does show the Snorkel installed however it is never shown raised. I was under the impression that I would be required to press a button as is shown in quite a few youtube videos in order to raise the snorkel. That is not something I can find in my installation. I have bound a keyboard shortcut [edited the keyboard.cfg file] for the snorkel but nothing happens when I press the key?
