How can I get code completion in Emacs? I got used to it by programming in Python's IDLE (althoug I'm more insterested in C now).
Also, under Eclipse, I put the mouse over a variable and Eclipse tells me where did the variable came from. I like it. How can I do something like it in Emacs?
I can't find it in Google or the documentation.
Thanks.
