Add the English necessary for toggle like this: `data-toggled="Truncate URLs"`

Then, in the javascript, you can totally avoid writing English in the code. And instead you can do something like 
```javascript
$('.urlvis_toggle a').on('click', function(event) {
    var toggler = $(this); 
    var current_text = toggler.text();
    var toggle_text = toggler.data('toggled');
    toggler.data('toggled', current_text);
    toggler.text(toggle_text);
```
