I have a input like this:
    <select name="born-year">
        [list of years]
    </select>

And I want to set this input to the first in selectedIndex, which usually is 
done by
    
    document.form.input.selectedIndex = 0

But this won't work:

    document.form.born-year.selectedIndex = 0

Probably because it has a '-' in it's name, right? How do I do it?

although you could do it with document.forms[0].elements['born-users'] it 
is a far far better practice to stick naming your elements using  
alphanumerics and underscores only.

I recommend always using the forms and elements collections, and use
square-bracket-notation:
 document.forms['form'].elements['born-year'].selectedIndex = 0;
I prefer this, since it keeps the namespaces (Javascript DOM names and
document names) separate.

I would suggest giving the tag an identical id attribute, then using the
getElementById() function to get it, thusly:

<select name="born-year" id="born-year">
    blah....
</select>

.....
.....

document.getElementById("born-year").selectedIndex = 0;

Using this method, you can directly access any id'd object in your page,
whether it's in a form or not. Obviously this means that if you have two
similar forms, they can't share identically named tags.

I recommend against making the name and id idential. It is safer to
distinguish the two, e.g., by using id="born-yead-ID" or something
similar.

Another reason to keep name and id separate.
