Before that :tag command works, you need to:
1. download the Vim source
2. make sure you have Exuberant Ctags installed (or at least a version
of ctags which will execute correctly the command
ctags -I INIT+ --fields=+S *.c *.cpp if_perl.xs *.h
when run from the src directory).
3. run "make tags" from the top-level Makefile, or if you haven't got
make, run the above ctags command in the src directory.
4. load one of the Vim source files into Vim. (running the same :tag
command while looking at the Vim help, for instance, would try to find a
help tag named do_one_cmd).
The above excerpt from the Vim code _proves_ that :% means :1,$. If you
aren't interested in the Vim source, :help :% _says_ that they are the
same (it admittedly doesn't prove it, but if something like that had
gone wrong for any length of time, either the help or the C code would
have been changed to make them both reflect the intended behaviour).
Best regards,
Tony.
