Hi,
have you understand what you ask ?
"all the symbols ... having a prescribed Head"
-------
what else should come out than Symbol ?
If you mean that the *value* of the symbols should have
a certain head than
ContextSelcet[context_String,hh_Symbol]:=
Select[ToExpression /@ Names[context], Head[#] === hh &]
will work.
Regards
Jens
