Moving audio event limits back into alignment with video

I have been using '/' to insert crossfades of audio across simple cuts in video, and it works great. But sometimes I want to move events around, and it would be really convenient if there were a keyboard shortcut that would take the edge of the audio for an event and snap it back into alignment with the edge of the video. Is there such a shortcut? I can't find one in the online help, but I'm not sure what to look for.

Right now, I just put the cursor on the edge of the video event, then slide the audio back into alignment, but if there's a way to do this with one key, that'd be great. I know about Ctrl-/ to change an audio crossfade back to a cut, but it only works when two events are butted together, not after you slide them apart.
