Triggers?

I seem to, apparently, miss something when it comes to triggers.
I'm trying to get one word light up in a different text-color, to make it harder to miss in "text spam". Using (whatever word) followed by an asterisk lights the entire line of text, which is NOT what I want, since it'll interfere with OTHER words in other colors.

Just using the word itself does nothing. No change at all, no matter what.

What am I missing?

Put the word on its own, and check the "regular expression" box.
