I've found something now!

In fact "methods(print)" lists, inter alia, "print.lm", and "?print.lm"
shows it in the "Usage" section as an item in a parameter list:

     print(summary.lm.obj, digits = max(3, getOption("digits") - 3),
           symbolic.cor = p > 4,
           signif.stars= getOption("show.signif.stars"), ...)

However, the parameter "symbolic.cor" is not mentioned anywhere else
in the rest of the help page, which is why I missed it!

(This is not the first time I've wished it were easier to track down
the detail you're looking for in R help, though this seems to have
been a particularly tough nut).

Best wishes to all,
Ted.
