+* ag
+
+  Evil bindings for [[https://github.com/Wilfred/ag.el][ag]] search result buffers.
+
+  Initial state for =ag-mode= is forced to =normal= so the buffer can be
+  edited with [[https://github.com/mhayashi1120/Emacs-wgrep][wgrep]].
+
+** Key bindings
+
+   Applied in =normal= and =visual= states.
