+** Search/Replace
+
+The /biggest/ thing I miss about my Neovim days is its ease of
+search/replace.  It didn't matter where the point was in the buffer;
+it could wrap around.  It had a little highlight to show you all the
+matching strings, /and/ it could show you what the replacement would
+look like.  =anzu= does /most/ of this, except the wrapping around part --
+=ctrlf= does the wrapping around okay, but I haven't really tried to get
+the two packages to play nice together.  Until then, I'll just use
+=anzu= and =isearch=, which is honestly a pretty good search package.
+
+*** Regex
+
+I search with regex by default.

+#+end_src
+
+I've switched =query-replace= and =query-replace-regexp= with their anzu
+versions, because of the regex thing.
