Highlighted Regions in Premiere CC
Today I was working on a project when I accidentally hit the X key and most the regions in my timeline became highlighted (see below).

I hit X again and it didn't go back to normal. It doesn't seem like an issue really, besides the fact that it's a bit annoying looking and I'm not sure what I did. For reference, here is what another project looks like (what I'm used to seeing):

Any information on what happened/ solutions would be much appreciated!
