I am not sure how it would be much different then clicking on the text, but then you have the benifit of having written the software.
I also cannot say I have needed to use the modal state display.
But playing with it now and the program below, clicking on any line with a g code and then showing the modal state seems to work, shows the proper S and T values. Why I J & Y show up under Other Modals but X does not is a puzzle.
But clicking on a line with an S or the M01 and then the modal display does not seem to update, it is showing the same S & T value it did the last time.
