Command for 'Snap On' only - for Macro use.

Noticed in your other video about having cursor be placed by mouse pointer. Another way for you might just be switching to the playback/scrub tool and clicking on a region. if you have a mouse with multiple buttons beyond the typical 2, just set one to playback/scrub tool.

You can also activate ‘Locate when clicked in empty space’ although not same as clicking right on the waveform, gets you pretty close. see pic.
