What it does is that it highlights that text in the page, with a yellow background color. Making the rest of the text difficult to read (your eyes are drawn to the very yellow highlighted part).
I love it, and have been manually creating such links every day since discovering the feature. One should be able to link to any portion of a page, and now one can, largely. The highlighting ought to be something a browser allows a user to customize, but I really wish Firefox (which I use about half the time) had the feature.
Agreed (I use Firefox), but (from being forced to use Chrome) you should be able to get the highlight to go away by clicking somewhere else on the page or by scrolling.
