XEmacs still has the edge over visual studio

nothing beats the paren highlighting ala (paren-mode 'sexp nil (paren))

to make a tagfile for a whole source tree add the following to you makefile:
(assuming nmake on WIN32 w/ cygwin)

tags:
cd ..
echo #!/usr/bin/bash > _tmpTags.sh
echo etags `find -iname "*.cpp"` `find -iname "*.h"` >> _tmpTags.sh
bash _tmpTags.sh
rm _tmpTags.sh


commands I'd like to try out:
M-tab, tag-complete-symbol
M-?i
tag-table-include-files
