What is this called? Or does it exist? A linear encoder as a slider button

I am looking for something like a linear potentiometer like they are used in DJ mixing desks. However, as a linear encoder. I know linear encoders exist for rail systems but does it exist for manual input?
Is there a name for it? Or does it exist at all?

I mean... what’s the application exactly? Within the scope of human interface devices, it’s unlikely you need digital caliper-level precision (which is what industrial linear encoders exist for). Rotary encoders exist to enable relative movement detection (i.e. endless rotation), which is impossible with a linear encoder. Otherwise, you just use a potentiometer.
And so absent additional information, I completely agree with the suggestion to use a linear potentiometer whose value you read with an ADC.
