Help finding images containing text

Hi,

I am trying to access controls inside a flash player. I have success finding play (thick arrow), pause (two vertical lines) and expand (arrows). However when I try to find images of speed buttons it is failing. I'm not sure how to upload images with this question t show you exactly what the buttons look like. They are square outlines with a textual speed inside them for example: 0.5X, 1X, 2X, 4X and 8X. I've tried various combinations of image and none are found. My region is fine and contains the buttons in question. Any ideas why this wouldn't work?

Thanks.

Charlotte
