shortcodes of the Membership pro plugin

Hello WPMU Devs,
I love the Membership pro plugin so much. It is so suitable for my site.
Now, I tried to customise my own page. I have some questions as follows:
1. How could you give me all shortcodes of the Membership pro plugin?
2. I tried to put a subscription button on some page. I tested! That member level was subscribed but the button did not have changes status. It is still "subscribe", it did not changed to "subscribed" or some words to remind members. What should I do?

I am looking forward to your favorable response. Thank you in advance!
