Captions for mc

Hi,

I’m trying to incorporate captions that appear when the cursor hovers over a word in my flash file. I was looking at this kirupa tutorial that i found on the subject, but i want it to be for text. Sometimes the text i want to caption is inside a movie clip (that has several frames with more text on those frames that i may want captions for–just to get an idea).

Should I put invisible buttons over each word, and have the caption in the “over” frame? Or is it better to use the kirupa tutorial i found? Or create a movieclip symbol, set its alpha to 0 and place it over the text? Am i just answering my own question? Any ideas?

Much thanks!
