GNU id-utils is great for that.  Run mkid to build a keyword database,
use gid/lid on the command line for searching.  This integrates with
vim's built-in :grep facility, see :help quickfix.txt, section 5.4
"Using :grep with id-utils".

ctags is the complement to that: it finds definitions rather than uses.
See :help tags.

I've been told that cscope can do the same thing (find both definitions
and uses), but I'm not personally familiar with it.

Absolutely.  '=' is the vim command for reindentation, and it works in
visual mode. I don't know about Emacs (<tab> reindents the current line;
I've never figured out how to reindent larger blocks -- I only ever use
Emacs when pair-programming with an Emacs user).

Another killer feature of both vim/emacs is keyword completion: start typing
a name, then hit a key to complete it, from the corpus of all the names
used in the current file/included files/the whole project (if you've
built a ctags db).  Sort of a dumb, but lightning-quick IntelliSense.
(vim also has smart autocompletion, called omnicomplete, but I rarely
use that -- Python programs are *very* hard to statically analyze).
