One useful key combo is M-/ (i think that's the default mapping). It
maps to dabbrev-expand. This is just a built in to emacs and just
searches your open buffers for sane expansions. The algorithm ends up
selecting the correct expansion. Hitting it repeatedly goes through
multiple options.

To search the TAG file you hit M-. (find-tag). I've never tried rtag (I
have used exuberant ctags to generate ruby and other language tag
files)

More instructions are available for a specific command if you hit M-h k
(describe-key) then the key sequence you want help on.
