But it does not. 3 (a + b) 1* -------- c d Selecting a Calc sub-formula doesn't highlight it. For example, in the stack entry above, I have selected (a + b) but other parts of the formula are still visible. All commands operate on the selected formula and it is selected as evident from the '*' after the number of the stack entry. It is not highlighted. This seems to be working fine in Emacs 26. It's broken in the latest Emacs versions: Emacs 27 and Emacs 28. I can confirm that it is not happening because of any of my configuration because I tried the same thing with `emacs -Q` and the result was the same. Best, -- Narendra Joshi
