Raw & scope tools in chop operators

I have somehow reached the raw edit tools and scope tools options within a CHOP. in the latest versions of TD. I can understand the raw edit tools (hot key s) mode, and it could be useful in specific cases; copy, move etc. some desired points. But I can’t understand what Scope tools (hot key s) option does or how it is used. I have not found any information about it either. Only this short thread mentions: https://forum.derivative.ca/t/channel-editor/4225/3![53|690x438](upload://zRT43jYfJnXIZq3ApxWNQWvBmnb.png)
