Hi Roberta,
Try disabling the Default Editor in Global configuration first, then open the backend settings of this Keyboard module and make sure that it has this output:
<div class="ja-keyboard-btns clearfix">
<a href="#" title="Up" class="ja-keyboard-up" tabindex="-1"><i class="icon-caret-up"></i></a>
<a href="#" title="right" class="ja-keyboard-right" tabindex="-1"><i class="icon-caret-right"></i></a>
<a href="#" title="Down" class="ja-keyboard-down" tabindex="-1"><i class="icon-caret-down"></i></a>
<a href="#" title="Left" class="ja-keyboard-left" tabindex="-1"><i class="icon-caret-left"></i></a>
<a href="#" title="Backward" class="ja-keyboard-playback" tabindex="-1"><i class="icon-step-backward"></i></a>
</div>
