I didn’t find this Help article helpful: Audio Clips - Audacity Manual.
as what it says just doesn’t work: one doesn’t select audio clips with the selection tool, because it doesn’t seem to know anything about audio clips, operating instead with audio data, not audio clips.
I have added some information about that preference for " Editing a clip can move other clips" to the section on moving clips on the Clips page you referenced.
This change is in the alpha manual for the next release (and will not show in the 3.4.2 manual)
I tried to do it, but I couldn’t find a way to select more than one clip. Neither Shift nor Ctrl help here, they don’t enable audio-clip multiselection
Or click on the left boundary of the left-most clip you want to move - then hold down Shift and then click the Select to end button in the Transport toolbar (the one that looks like a fast-forward on a tape recorder or VCR).
I’m new and still learning, but I found creating space at the end and then moving over the last clip opened space for the second to last and because there was space I could move right. It’s a pretty kludgy time cosuming way to do it, but like you I couldn’t move all the clips over to the right at once.
That’s difficult to achieve when the length is big as in my case (40 minutes of recording). So basically to see the whole thing I zoom out, and at that zoom level the details get lost
But the second approach worked. I’ll post a video.
