Btw, it was surprising to me to see that very little code in Emacs actually takes advantage of this command-substitution facility in help-echo; most help-echo strings that mention commands actually hardcode the default binding.
Also related is the fact that help-echo allows kinds of values: strings or functions. In Flycheck's case (the one I know the best), it would be enough to say that help-echo is only passed through substitute-command-keys if it's a string, but not if it's a function (the reasoning being that it's easy to run the substitution inside the function, if needed). Of course, shr and Flymake would then need to switch to using functions instead of strings, as well.
Clément.
