Very useful for dialog editing and AFAIK not documented specifically:
You might know the situation where an actor, while speaking, turns her or his head. The sound changes dramatically and you want to apply some EQ on just a small section of a clip. So you chop it up, hit your KC (another situation where its a huge time saver) to bring up your preferred offline EQ, adjust and hit process.
Now, as your clip is still selected, all you have to do is hit “X” (the default KC for Crossfades) and Crossfades will be created at the beginning and end of that clip. There is no need to select the clip before and after the one that you processed !
