[Vol-users] using volshell in volatility 2.3

I'm a noob with Volatility, so please be patient. I am working through some samples I found online. I've identified where I think malware was injected into a process by following this tutorial: http://volatility-labs.blogspot.com/2012/10/reverse-engineering-poison-ivys… My question: once in volshell I get many errors in my python code. How do I enter a "tab" in volshell? Since Python is so dependent on indentation, I cannot follow the rest of the tutorial as I cannot get past the "for addr in addrs" line.. Thanks.
