Yes, the form remrule("+", ?\+rule1); works fine. Thank you.
@Richard
Fine, now I know to whom ask about any problem with 'tellsimp' :) Thank you
for the link. When possible I will read that paper.
But note that I am right now just at a stage of a first time full reading
through the Maxima documentation, taking profit of the new wxMaxima document
format that conveniently saves my input/output for command tests.
So, do expect some more questions about similar problems with the manual
shortly.
