Split Layer Shortcut in After Effects

Splits the selected layer into two at the current playhead position.

Far more efficient than duplicating and trimming manually. It's the standard professional workflow for when you need to change a layer's properties midway through its duration without affecting the first half.

Position the playhead where you want to split a layer. Select the layer and press Ctrl + Shift + D. The layer will be duplicated and trimmed, with the original layer ending at the playhead and the new layer beginning at the playhead.
