Could someone do a quick video demo of the new range editing utilities and how they can be use?

even a gif animation. I’m still on 10.0.6, would like to see this in action… might twist my arm to update.

Do you mean the combined object and range tools? There’s a video on the Cubase channel about that:

No I mean the Range Selection functions in the new 10.5.2.

New Range and Event Editing functions [Pro/Artist]
We have added some new functions to the Range Editing menu: Range to Next Event/Range to Previous Event, Enlarge Range to Next Event/Enlarge Range to Previous Event, Cut Head/Cut Tail, and Set Spacer between Selected Events. Cut Head/Cut Tail can especially speed up your audio cleanup workflow. There are no default key commands assigned to these functions, so feel free to adjust them to your workflow.
