I want to make it so that when I am not pressing any buttons, a function happens. Here is what I have, but it doesn't work 
public void act() 
    {
        if (Greenfoot.isKeyDown("any") == false)
        {
            moveDown();
        }
    }

The only way to check for "any" key down is to check each possible key individually. Maybe you can limit the number of keys that you want to check somehow. Without more information as to what you are actually wanting, it is difficult to give you advise on the best way to handle the issue.

Are you attempting to add an improvised gravity to your simulation? If so there are certainly better techniques for implementing such features.

if the left, right, up, and down keys are not pressed, then the function happens

So, basically, you want something like this: 
boolean up = Greenfoot.isKeyDown("up");
boolean down = Greenfoot.isKeyDown("down");
boolean left = Greenfoot.isKeyDown("left");
boolean right = Greenfoot.isKeyDown("right")
if (!up && !down && !left && !right)
{
    // perform function
}
