In CS 5.5 at least, you had the possibility to to make fades in and out in both video and audio by CTR + clicking the middle line in the track, and move the points created by the click.
In CC I can only find it for audio. Am I missing something, or has the feature been taking off.
Right Click on clip in timeline. Select "Show Clip Keyframes" and tell it which one you want to see.
Much functionality is hidden under the wrenches (display settings),contex menu and panel menu.
