Lock layer's position on timeline

Question

I want to know if it is possible to lock only a layer's position on the timeline (so it is still editable for all it's other attributes)
I am working and keep accidentally selecting objects on the timeline and dragging them when I don't mean to. I am doing a lot of attribute animating and need to regularly switch between selections. It would be helpful to simply lock all layer's locations on the timeline so I can't accidentally move them.

I am often selecting via the timeline rather than the left of the timeline cuz I can visually see the elements I am looking for better by where they start and end on the timeline.

All help appreciated! 🙂

It would be great if the Position property had a lock switch of it's own.

You could use an expression to set the Layer's position.

Select the Position property and the choose Animation > Add Expression.

Replace "transform.position" with the following:

// Set the X and Y position

xPosition = 300; // Replace this value with your desired X position

yPosition = 300; // Replace this value with your desired Y position

// Apply the new position

[xPosition, yPosition];

If the Position needs to animate, you could link the xPosition and yPosition to Slider Controls (Effect > Expression Controls > Slider Control). That may limit you to linear spatical keyframe interpolation, though. Someone better at scripting may have a more flexible suggestion if the layer needs to animate with Bezier, Continuous Bezier, or Auto-Bezier spatail interpolation.
