How do I intelligently re-indent Clojure in Emacs?

I'm new to Clojure and new to Emacs.

Is there an Emacs short-cut to intelligently re-indent the whole file? if not, is there at least a way to indent selected regions left or right?

I feel like I'm back in the stone age repeatedly pressing the arrows

Use cljfmt for many configurable ways to reformat/reindent. It has an Emacs plugin, but also can be run via lein.

When you capture data from a sequence like C-u C-c C-e (cider-eval-last-sexp), the raw data output to your buffer can be unwieldy to inspect/work with. And the normal code-indenting commands (mentioned in answers here) don't handle it well.

For handling results from such evaluated expressions, try cider-format-edn-region.

As a concrete example, have you ever tried reformatting your ~/.lein/profiles.clj? This is pretty hard to do and keep consistent, until you discover cider-format-edn-region. Take caution that it will, however, remove any comments.
