Those using text files might want to try something like this.
Create a little html file with some form fields, and this piece of code.
Code:
<script>
function doCopy(what){
Copied = what.createTextRange();
Copied.execCommand("Copy");
}
</script>
Put this command on the form fields.
Code:
onclick="doCopy(this)"
Clicking the field dumps the information to the clipboard so you can just paste it on the submit pages.
