Studies: Overlay - shifting L/R with keyboard

Q: When moving the chart forward/backward, one bar at the time, with the keyboard comma and period buttons, only the overlay moves while the host chart is static. In Properties for chart overlay, this is noticed by "Shift -L/R+" changing value accordingly. This makes me uncertain if the Main/Overlay charts are synchronized or not. It would be nice if they moved together.

A: This is the intended behavior, where the comma and period keys will move the overlay relative to the host as a keyboard shortcut to avoid going to the study property form to adjust the Shift L/R parameter. You can drag the chart left and right with the mouse to move both host and overlay together when the overlay property for 'Lock Shift L/R' is checked.
