Show an Object's element

hi guys!

i have lots of objects, within them are lots of others ( MovieClips, numbers, strings )
like this:


var O:Object = {
   oneMovie:MovieClip,
   someString:'hello you!',
   nums: { numOne:13 , numTwo:12.46 }
}

my question is:
is it possible to list those elements when i start typing with an IDE or AS Editor ? if it is what’s the name of that?

…so i’ll type " O. " -> then popup a menu with the object’s elements like with a MovieClip and the methods of the MovieClip

thx all!
