Option to Disable Accidental Slip Editing in the Timeline

Hi,

I'd like to request an option to disable slip editing when dragging the mouse over the areas before or after a trimmed layer in the After Effects timeline.

Currently, when you click and drag in these areas, After Effects performs a slip edit, shifting the source footage's In/Out timing without changing the layer's position or duration.

This behavior is extremely frustrating when working with compositions containing many layers. When trying to move or rearrange a layer, it's very easy to accidentally click on the wrong row and unintentionally slip-edit another layer instead.

These accidental edits can easily go unnoticed and cause serious timing or synchronization issues.

Suggested improvement:

• Add a preference to disable slip editing through regular mouse dragging.

• Alternatively, require a modifier key (such as Alt/Option) to perform a slip edit, rather than allowing it by default.

• Keep normal layer selection, trimming, and dragging behavior unchanged.

Slip editing is certainly a useful feature, but it should be possible to disable it or make it a deliberate action rather than something that can happen so easily by accident.

Please consider adding this option in a future update. It would make timeline editing significantly safer and less error-prone, especially in complex compositions.

B.R.

Stephane.
