Bookmarklet help

How can I make a bookmarklet, that when I press it it inserts a specified text into the selected input field?

Have you went on bookmarklet (http://www.bookmarklets.com/) page already.

<form name = "myform">
<input type = "text" name = "txt1" id = "txt1" size = "40"><br>
<input type = "button" value = "Click here to insert text" onclick = "insertText()">
</form>

<script type = "text/javascript">
function insertText() {
var addtxt = "The text you want to insert";
document.myform.txt1.value = document.myform.txt1.value + addtxt;
}

</script>

Haha. I should have admit that i'm confused on what "bookmarklet" suppose to be.

Yes, so is the OP!

I know what a bookmarklet is >: (. What I want to do is have a link in my bookmarks to insert the HTML entity for a blank space, to make blank posts in a forum that I go to often so that I don't have to manually type it. The HTML entity I'm refering to is & # 3 2 ; of course.
