text is a tough way to do audio — ⇧ SHIFT — ⌃ CONTROL — ⌥ OPTION — ⌘ COMMAND

The documentation is clear, except for the difference in wording.

Selection Start to Next Transient: The selection start is shortened to the right, up to the following transient marker.
Set Region Anchor to Playhead
It is difficult to find a definition of “region anchor”. The simplest visible sign is the anchor indicator that you see in the Project Audio Browser. Typically a region anchor is at the start position of the region, but it can be moved.
The anchor can be used when regions are moved. If I set the region anchor to the middle of a region I can move the region to a different location typically placing the region anchor position at the playhead position.
Move regions in the Logic Pro Tracks area — Apple Support
If more than one region is selected, all subsequent regions are moved. For audio regions, the region anchor is placed at the current playhead position.
Lock Position in Track when moving Anchor ⌃A
I have still not found a decent description of “the Anchor” and how it is used…the best that I can discover is that the anchor is what gets aligned to the playhead when adding regions to tracks.
Someday I will edit audio in Logic.

Anchor: Indicates the absolute start point of the audio file.
Map performance patches in Logic Pro — Apple Support
Performance patches can also exhibit interesting characteristics that differ when playing live and when playing back a region. When you play a note live on the keyboard, the sample is played from the sample anchor—a marker that represents the musical focus of the sample, or the position that should land on a beat. When you play back recorded MIDI events, however, the full sample is played, even if it starts before the note on event. This behavior leads to more natural-sounding instruments—for example, the sound of a tambourine that is generated before the actual palm hit.

Shorten the current selection in the audio file to the left.

Selection End to Previous Transient: The selection end is shortened to the left, up to the preceding transient marker.
Selection Start and End to Previous Transient ⇧⌘←
This command advances the selection points to the previous transient. From this point you can move the start or end as needed to select the audio to work with.
I don’t edit much, if ever. I wonder if group editing is honored?
Group editing in Logic Pro — Apple Support
Group editing allows you to perform many editing, arrangement and timing operations on all group member tracks simultaneously. For example, you can combine the comping feature with group editing so that every comp uses the same takes. You can move, resize, and arrange regions for all group member tracks together. You can also adjust the timing of the group, ensuring the group remains in time.
Apparently Group Editing is only using the Track Editor, not the Audio File Editor.
