What are commonly used gvim shortcuts?

What are the most commonly used shortcuts used in gvim for C programming? For in开发者_如何学编程stance, how can I perform function name auto completion (without using the default word autocomplete). Could you please provide a cheatsheet or a tutorial?

I use snipMate alot for C++/C programming:

For function name auto completion you're probably stuck with ctrl+n ctrl+p or you can possibly try to get some omnicompletion working

This is what I was looking for: a vim cheatsheet!
