I do not find a keyboard shortcut for, from a beat, going to the NEXT or PREVIOUS one.
When we have many lanes or when the next beat is billow/above out of screen, it is cumbersome and effort/time consuming figuring out the next beat, (In both cases between zoomed view and all inclusive view) : we need to take time comparing beat positions.
If we want a LASTING clue displayed, we could enable/hide an arrow towards the next beat or from the previous one (just the one we are interested in)
There could be another mode:
For avoiding many displayed arrows, only one arrow at a time would display towards the next beat and from the previous previous beat (just the one we are interested in)
Also, clicking each beat, in sequence, could be enoying.
Solution:
We could just click shortcut for going to next/previous beat (I did not find it in the doc).
Just hovering the beat, entering by the side could activate the arrow
(Left side: toward previous beat, right side: next beat)
It would disappear when either:
-we hover another beat (Entering from any side, even if hovering the actual beat),
-or click a beat,
-or click the white board background
We can then scroll the white board to the next or previous one.
This would accelerate following the story, while reviewing it or sharing it with somebody.
(Avoiding forgetting/unnoticing a beat)
We could then select which one we need help for, just by hovering on it, by a left/right side.
But remains the problem of beats out of screen or too far: we might not notice them. We might want a lasting clue that the next one is out of screen (out of what we can visually compare) So, when there are beats out of screen, we could systematically have arrows going to and from the hidden part.
