Once I select a data point in my plot using the Data Cursor tool, it would be very useful to be able to switch back and forth between consecutive data points using the keyboard. It seems, however, that the arrow keys (and a few other keys I've tried) do not advance the DataCursor to the previous/next data point, as I hoped. Is there any keyboard shortcut that can be defined for this?
Running Matlab R2016a on Windows 7.
Many thanks!

As of r2020b, keyboard control of datatips is supported by several plotting functions such as plot() line() and surf() but not by scatter(). See this answer for a workaround using scatter.

You are probably using 'brush' which is the first (and default) option in the large, red rectangle box. Switching to 'data tips' (second option from left, boxed in small red square) should allow you to toggle between data points using keyboard arrows. You have to mouse over that area to see the options. Hope this helps.Data Tips.jpg
