Answer 1

Yes, this is completely possible.

var isInventOpen:Boolean = false;
function openCloseInvent(e:KeyboardEvent):void
{
    if(e.keyCode == Keyboard.SPACE && isInventOpen == false)
    {
         //Open Inventory
         isInventOpen = true;
    }

    if(e.keyCode == Keyboard.SPACE && isInventOpen == true)
    {
         //Close Inventory
         isInventOpen = false;
    }
}
