How to mark a tooltip-containing word in a paragraph?

I have a sentence in which one word has a tooltip. The data in the tooltip is supplemental and putting it into the main UI isn't required.

However, how can I mark the word to notify the user that it has a tooltip? I've tried marking the word with an underline and blue color, but it looks too much like a link (which it isn't).

Below is the image of what it looks like now:

Thanks!
