There's a bunch of ways with which to emphasise part of a written sentence.
You can, for instance, italicize it, like this. Or you can make it bold, like this.
You can also add something extra, such as underscores, like _this_, or perhaps asterisks, like *this*.
Another way to achieve a similar result is to capitalize something, like THIS.
And you can also make some *VERY* _interesting_ *combinations*.
There's one thing you shouldn't do, though:
_*EXAGERATE*_
