Formatting per slide

Is it possible to change the formatting per slide? I like to keep the text as large as possible but sometimes a line might be 1 or 2 characters too long and causes a single word to wrap. I would like to be able to tweak the font size just for the one slide.

It is not possible to modify a slide while keeping a template applied. You'll either need to remove the template altogether or modify the template so that the font is a little smaller. Another alternative is simply to split the overflowing line in a place that lyrically and melodically makes sense. You'll have an extra line but you won't have to adjust your font/template.
