retime primary clip without moving connected clip?

Is there a quick way of keeping the connected clip above from moving when you change speed of a primary storyline clip below? Using ~ doesn't work. Thanks.

You would have to connect it or a storyline to some other point in the timeline.

Yup.
Another request for Mr. Cook...

Work Around is to lift the clip from the primary (command-option-up-arrow), then retime, adjust the gap if necessary to drop the clip back down into the primary (command-option-down-arrow).

It's one of those grey areas where the basic design feature of connected clips is somehow tricky. Because to accomplish what you want is to connect a clip not to another clip anymore but to the absolute time of your timeline.

Yup. Something like holding down the ~ key would be ideal.
