Re: why are "references" restricted to symbols for which we have definitions?

Thanks Shigio.

So

global -s

works well and gives me all the symbols, but I get too much output as every
single variable , typename etc all get printed. I wish it were possible to
restrict to symbols that are function/method calls.

(One nice thing about universal ctags is it shows the "kind" of entry a
tags line is (eg, macro, function, etc.) I can then restrict a tag search
to entries of a certain kind, a very useful thing at times .
