How to put the Syndication Feed Module Icon in theTop Menu

Question

I would like to place the Syndication Feed Module in its simpliest form (only its icon), at the end of the top-menu of a site (position-1 of the protostar template). Unfortunately, when affected to position-1, the module appears on a new line below the menu items.
Does anyone have an idea of the nicest way to do that ?
Help would be greatly appreciated.
Here is what I get:

Answer 1

Here is your solution:

For you nav element add this CSS:

ul.nav{
    display: inline-block;
}

For your feed link add this CSS

a.syndicate-module{
    float:right;
    line-height: 34px;
}

If you want the feed icon to be left aligned to the menu instead of floating to the right change the CSS to this:

a.syndicate-module{
    display: inline-block;
    vertical-align: top;
    line-height: 34px;
}

Image links for you to see the difference:

Left Aligned

Floated Right

Answer 2

Following Terry idea, I finally got it! The idea is to use display:inline-block for both ul.nav and a.syndicate-module and also to give a width to ul-nav.
The menu can then have as many lines as he wants, the RSS icon will be displayed on its right.
So:

 ul.nav{
     display: inline-block;
     width: 50%; /*to have a menu with many lines, 98% is the right value*/
 }

and

a.syndicate-module{
    float:right;
    vertical-align:top;
    display: inline-block;
}

gives:

Many thanks Terry, could not have found this without your help !
