user2365: When I have audio and video tracks de-synchronized, is there a way to make them synchronous?
A workflow:

Add a video+audio track to a project;
Crop a small Event in the middle and remove the rest;
Uncheck Ignore event grouping option;
Drag one of the tracks sideways;
Note the audio track gets reddish background to indicate it is not synced to Video.
Resize Video and/or Audio Events so that original start/end timestamps get lost;

Now I need to get Audio synced back to Video.
Obviously, dragging Video or Audio will not work as I have resized both Events individually.
How to get Audio back in sync, probably by losing cropping?
I'm aware about opening the Event in the Trimmer and re-dragging the Audio track from there.

user5074: This does it for me (see the screenshots):

Set the cursor to the beginning of the audio event.
Drag the beginning of the audio event with the mouse to the beginning of the original clip (note: the cursor is still positioned at the cropped beginning) (screenshot 2)
Cut the audio event at cursor position (press S)
Repeat step 1 to 3 with the video event (screenshot 3)
Now you can easily synchronize video and audio by aligning the events (screenshot 4)
Delete the beginnings. (screenshot 5)
