I'm designing a timeline similar to the one found here:
only I have a lot more instance of the markers along the timeline. I want to use the same button symbol for all the
markers and change the text in a pop up info-box that shows up for each one depending upon where you are along the time line.

I'm not very experienced with actionscript, but I figure there's got to be an easy way just based upon the screen pointer position or something like that.

The data is fixed for each marker and doesn't have to change.
