list of Mma commands with specified properties

  • To: mathgroup at christensen.cybernetics.net

Hi Group;
	A student asked me "Which Mma commands have the option 
of allowing Trig->False so that she could set Trig->True?"
	This question raises a more general issue which I pose to 
you in the form of two questions:
	(1) How does one ask for a list of commands which have a
	    specified option such as Trig->False ?
(I won't clutter cyberspace with my makeshift solution, since I'll
bet there is a "professional" way to do it.)
	(2) Same question for attributes, say for instance, Listable?

Another student asked this question (actually it was me):
	(3) Is there a way of forcing the front end to produce  
	     output in MatrixForm in a given Mma session rather than
	    a list of lists (of equal length) as it does now?
This is of value when one knows in advanced that a particular 
session will be dealing entirely with matrices.
Jack
