Cutting(preview window

At page 13 of the manual of TS-DOCTOR there is an illustration that i'am not able to find, what is the procedure.
Furthermore is possible to have an outlook where are placed the commercial breaks?

Press on the second button on the left side at the bottom of this window to get a thumbnail view (left to the screenshot button). That makes it easier to find the commercial breaks.
