Quote Hello,
I want to be able to move the line separating two adjacent clips. Of course I can shorten one and lengthen the other... but in Final Cut, there is a function that allows you to move the separation between two clips in a single operation (of course as long as the clip that is "lengthened" by the move is long enough). Does this function exist in PD?

You can right click on a clip on the TL and select from the available options. Selecting ‘Remove, Fill Gap, and move all clips’ will move all of the clips on multiple tracks in your project up, keeping them all in sync. Also, you can hold down your left mouse button on an empty track on the timeline and then move your cursor. You will see a box start to emerge. Every clip that that box touches will be selected. You can then move all of those selected clips at the same time. Also, if you click the first clip in the track to highlight that clip, then hold down the shift key and click the last clip in the track, that selects the entire track and everything moves as a single unit when you drag anywhere within the track.

Highlight the clip you'd like to lengthen, place the cursor on the timeline at this split line on the clip, you will see a double arrow, left mouse click and drag to length, which will essentially shorten or trim the adjacent clip. When you release the left mouse click, a contextual menu will appear with some choices, chose "Overwrite" and one clip is lengthened (if video content was available) and the other clip is trimmed.
