how to do complete script function in Mono IDE?

I has been learning unity for two weeks. I use javascript to write test cases with MonoDevelop IDE help at the beginning. Before this I used Eclipse to write Java code. It make me uncomfortable to used compared to Eclipse, maybe because I know about Mono IDE little, so I have some questions about It.

  1. how to auto completion the function name ?
  2. how to promt the parameter list?
    Or exist any better IDE to write unity javascript?
    By the way, I has been using C# instead of javascript, because VS is more powerful.

I know this isn’t that helpful, but by default, when MonoDevelop installs with Unity, the autocomplete is already enabled (at least I know it is for C#). You simply start typing your function or variable names and it pops up instantly. When you type a function name and then type the first opening bracket, it automatically pops up with the parameter list and it even changes based on the different input data types to correspond with other overloads of that same function.

In short, MonoDevelop does have these features but it sounds like perhaps they are disabled on your machine and you need to enable them.
