Does anybpdy know how to create a Logic for select track ? ( Or Focus track )
Klaus description is "close" to working solution

The action list should be
1. Strip
2. Function / Select Strip
In the "Strip" there are quite some options:
a) "Track/Bus" absolute (<First>) strip (f.e. +1 to select the strip number 2, strips are counted from 0...)
b) "Track/Bus" WAI (color bar left side in the Track View, under strips in Console view, you can move it with mouse) related strip (f.e WAI +2)
c) Current focus related, f.e next is <Current> + 1
d) If you create Software Set "My tracks" (in the Options Tab) and add "VOX" State there, you can choose it as an option in the "Strip" action. So you can select "VOX" (strip name), independent from where you move it.
For that to work, the focus should be in the correct pane. If you are currently in the bus pane, focusing different Track will work, but the result will be "invisible". To also change the pane, you will need another actions (due to a bug in Sonar it is a bit more complicated to make the pane switch reliable).
But as I have already mentioned, just let me know on my forum which button definitions you need and I will make an example preset for that (this forum does not have attachments and this discussion is not directly about Sonar...).
