hey guys, i was wondering if anyone knew how to selectively highlight text in word?

what i mean is: when you left-click and drag on a sentence. then you've highlighted it and you can either change its font or size or whatever... you can also hold shift and left click...

HOWEVER, you CANNOT skip lines or every other word if you wanted to.. it will ONLY highlight the ENTIRE thing....

HOW do i SELECTIVELY highlight what i want to highlight in a text?
