+USAGE:
+    fzf_configure_bindings [--FEATURE[=KEY_SEQUENCE]...]
+
+DESCRIPTION
+    By default, fzf_configure_bindings installs mnemonic key bindings for fzf.fish's features. Each
+    feature's binding can be customized through a corresponding namesake option:
+        FEATURE            |  MNEMONIC KEY SEQUENCE        |  CORRESPONDING OPTION
+        Search directory   |  Ctrl+Alt+F (F for file)      |  --directory
+        Search git log     |  Ctrl+Alt+L (L for log)       |  --git_log
+        Search git status  |  Ctrl+Alt+S (S for status)    |  --git_status
+        Search history     |  Ctrl+R     (R for reverse)   |  --history
+        Search variables   |  Ctrl+V     (V for variable)  |  --variables
+        Search processes   |  Ctrl+Alt+P (P for process)   |  --processes
+    An option with a key sequence value overrides the binding for its feature, while an option
+    without a value disables the binding. A feature that is not customized retains its default
+    menomonic binding specified above. Key bindings are installed for default and insert modes.
+
+    In terms of validation, fzf_configure_bindings fails if passed unknown options. Furthermore, it
+    expects an equals sign between an option's name and value. However, it does not validate key
+    sequences. Rather, consider using fish_key_reader to manually validate them.
+
+    In terms of experimentation, fzf_configure_bindings erases any bindings it previously installed
+    before installing new ones so it can be repeatedly executed in the same fish session without
+    problem. Once the desired fzf_configure_bindings command has been found, add it to config.fish
+    in order to persist the bindings.
+
+    The -h and --help options print this help message.
+
+EXAMPLES
+    Install the default mnemonic bindings
+        \$ fzf_configure_bindings
+    Install the default bindings but override git log's binding to Ctrl+G
+        \$ fzf_configure_bindings --git_log=\cg
+    Install the default bindings but leave search history unbound
+        \$ fzf_configure_bindings --history
+    Alternative style of disabling search history
+        \$ fzf_configure_bindings --history=
+    An agglomeration of all the options
+        \$ fzf_configure_bindings --git_status=\cg --history=\ch --variables --directory --git_log
