Thanks in Advance to anyone who can help:
So, I'm rendering and all of a sudden my timeline looks like the image below:
I know I bumped something, held down a shift that I didn't realize, but now I can't get it to go away!!!! It's actually a cool feature, but it's tacking up what little room I have for my timeline on my 15" MBP
There is a toggle on the bottom left corner, the icon is just two horizontal lines. It toggles keyframes on and off, so you can makes changes to them in the timeline. Click on it and they grey stuff (which are there to mark individual frames) as well as the blue horizontal line (on which your keyframes, if you have any, should sit) will go away.
