I often use reveal.js (or slides.com) to made presentations. 

I like to use bullets (unordered lists) to organize information, but often don't want the circles. This can be accomplished using the CSS editor to style the bullets with the following:

ul {
list-style-type: none;
}

In order to only apply this to certain elements/text blocks, simply create a new target and set the Class Name to 'nobullets':

.nobullets ul {
list-style-type: none;
}
