WaveLab offers helpful options for moving and crossfading clips.
Ripple
When you move a clip, ripple determines whether the clips to its right are moved along with it. The ripple options are available via the Edit tab of the Audio Montage window.
- Track
-
If this option is activated and you move a clip horizontally, all clips on the active track that are located to the right of the edited clip are moved as well. This option also applies when moving or resizing clips, and when inserting or pasting more than one clip at a time.
- Global
-
If this option is activated and you move a clip horizontally, all clips on all tracks that are located to the right of the edited clip are also moved. This option is taken into account when moving or resizing clips, and when inserting or pasting more than one clip at a time.
- None
-
Deactivates the Ripple feature. As a result, only the selected clip is moved.
By default, when you move clips on standard tracks, Ripple is not applied to clips on reference tracks. However, you can include clips on reference tracks in Ripple processes by activating Global Ripple Affects Reference Tracks via Additional Options 
at the bottom of the Ripple panel.
Crossfading
The following crossfading options are available via the Fade tab of the Audio Montage window, in the Options section.
- Overlaps
-
This pop-up menu allows you to set the automatic crossfading behavior.
-
If No Automatic Crossfading is activated, no automatic crossfading is performed for any overlapping clips.
-
If Free Overlaps is activated, automatic crossfades are created when a clip overlaps with another clip on the same track. The length of the overlap determines the duration of the crossfade.
-
- Options
-
-
If Create Default Fades in New Clips is activated, all new clips assume the default fade-in and fade-out shape and length. For clips that are created by splitting a clip, only the default fade time is used.
