Emphasis on Words

I love your program but I was wondering how do you put special emphasis on certain words to make them stand out?

What do you mean by "special emphasis"?

Just put a duplicate of the word... For example take the following list

Cat
dog
mouse
chicken

If you dog to stand out more, just add it another time, each time you add it the more it stands out.

cat
dog
dog
mouse
chicken

would make dog bigger than the other words.

Is there a way to make "dog" stand out in a way where it is not repeated more times as well? For example, I'd like dog to be just displayed once, but significantly bigger than all other words. Is that possible?

In "tag source" -> Manual edit: here you can put weights on words!

I'm trying to do the same. One word only showing once, but large. If you give it a higher weight, it shows up more also. Is there a way around this?
