I’m afraid we don’t support moving the rollover line by key-press, but we do have a rich Custom ChartModifier API where you can create or customise your own ChartModifiers.
I recommend having a look at Custom ChartModifiers – Part 1 – Creating a Custom Rollover Modifier as well as the second part of this article Zooming In / Out on Key Presses as this may give some inspiration.
Alternatively, you may find it better to use our built in VerticalSliceModifier to display a ‘rollover line’ and then subscribe to key presses on the parent window to move it (update its position) instead of use a Rollover line.
Hope this helps. If you find a good solution, please post it below so it can help others!
