How to add a submit button to search?

[snowmanrene]

<div id="search">
            <form method="post" id="searchform" action="{$baseurl}/index.php" >
                <input type="hidden" name="menu" value="search" />
                <input id="s" class="rounded" type="text" name="query" />
		<input type="submit" value="search" id="searchsubmit" />

            </form>
        </div>

Just tested it to be sure and it works.
