Keyboard shortcut to move DataCursor tooltip to previous/next data point

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!

The arrow keys work for me on Mac, but I would need to recheck whether they work for programmatically creeated tool tips instead of just for ones created by clicking on the plot.

Funny: I created a simple test plot, and there the arrow keys do move the data cursor tooltip, but not in my original plot, which is made up of 60 subplots (each taking up a thin horizontal line); that plot also has a few lines drawn using the 'line' function, but still I don't understand why that means the data cursor should not be movable.

Is it possible that hittest or pickableparts has been set false?

Not by me! Typing the first command returns the lines below, and typing the second returns an error.

Line with properties:

              Color: [0 0.4470 0.7410]
          LineStyle: 'none'
          LineWidth: 0.5000
             Marker: 'o'
         MarkerSize: 4
    MarkerFaceColor: [1 1 1]
              XData: 177972
              YData: 0.5000
              ZData: [1x0 double]

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.

Thank you!

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.
