All tracks have been recorded simultanuously, they all have the same
start and end point. What more is required to make them 'equivalent' ?

If the screen is filled you can't even start the selection: there is
not point above the first track to click into.

So *how* do I select all regions at either the playhead or the mouse
position (you may assume they are all 'equivalent') and nothing else ???
And why, if A and B are separated by a millisecond, 'u' selects either
A or B (depending or where I click), but when I move B so it overaps A
it selects both ? Does the 'edit range' depend on this overlap ? Again,
I've tried to understand what Ardour is doing in such cases, but it just
does not make any sense at all.

That is not the question. The question is why e.g. clicking on the first
B region selects it correctly, and Shift-click on the second B region
selects and adds *both* the A and B regions on that track.

which means that is useless in this case.

Note that the 'primitive' hard-disk editors that I was using in
the late 1980's had no problem with any of the things I mentioned.
And they did not even have any form of 'graphical' representaion
of the tracks. But you could edit using them almost as fast as using
a razor blade on tape. The only time wasted was the transfer from DAT
to hard disk, but that could be done while you had lunch or a coffee.
The fundamental problem here is that Ardour is completely unaware of
what a user is trying to achieve. It provides elementary operations
much in the same way as an assembler provides machine instructions.
But it has no idea at all of higher level concepts, such as 'the user
is trying to make an edit (short crossfade) between two sets of regions'.
Apart from the selection there is no 'context' to any edit operation,
and consequently no intelligence either.
There are three of them, and Alleline.
