For stay concise i have put a link to your description! ;)

And put this animation...in fact that's like an electric game train!
Mode "button" is for speedy distress cases! Like detach a wagon! :)

One more try :-)

Switch node:
The Output is connected to either the top input, or else the bottom input, depending upon:

Switch mode:
Left click toggles between top input and bottom input.

Changing to Button mode, in info window, connects the top input.

Button mode:
The pre-existing connection is with the top input.
Left click with HOLD, connects the bottom input, until hold is released. Then the top input is re-connected.

Pilou, you are doing an excellent job!

Added these last precisions with the Switch mode from you for be exhaustive :)

Some infos about these Modes : Long, short, cross, average, repeat (here for the node Line )
It's for Arrays of values or it's another things ?

Max did some explaining in the nodeeditor thread a while back.

About 8 months ago, I went through the thread, and copied portions of relevant explanations (documentation) to a notepad++ file.
(Whether it was understood or not :-)
I think Karsten made some explanations as well...

These selection modes must be known by computer programmers:
...Looping Through Multiple Lists

...descends through lists combining all elements into one ... dim=c(3,4,2); elements of x recycle if x is not long enough...

Google: "combining multiple lists Long, short, cross" yields Lacing type (short, long, cross), in programming.

Then Lacing becomes how to tie shoes...:-)

Ok that is that for the Array of values that you input inside the Panel info (and i suppose also for multiple selection)

Now rest to have the little animations for cross, average, repeat !

The funny of that is you have these same modes ( or less) for the Points of the lines itselves! (not only for the lines)
So many combinaisons possible! :)

I begin to understand! :) here for cross...each start line point go to each end line point (if Points itselves are all "Long" ! )

Ok I have nailed it! :)

All points are "Long"

Ok all is mastered! (my headache also! :)

And of course that change if you modify the Points modes itselves! :)

So 2 (modes start pts) * 2 (modes end pts) * 5 (modes lines) = 20 possible combinaisons of modes! (for the moment)

here only the "Pts" so 4 variants with "Long Lines"

Added Node Line (English) + paradigmatic Modes :)
