+USAGE:
+    fzf_configure_bindings [--COMMAND=[KEY_SEQUENCE]...]
+
+DESCRIPTION
+    fzf_configure_bindings installs key bindings for fzf.fish's commands and erases any bindings it
+    previously installed. It installs bindings for both default and insert modes. fzf.fish executes
+    it without options on fish startup to install the out-of-the-box key bindings.
+
+    By default, commands are bound to a mnemonic key sequence, shown below. Each command's binding
+    can be configured using a namesake corresponding option:
+        COMMAND            |  DEFAULT 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 Processes   |  Ctrl+Alt+P (P for process)   |  --processes
+        Search Variables   |  Ctrl+V     (V for variable)  |  --variables
+    Override a command's binding by specifying its corresponding option with the desired key
+    sequence. Disable a command's binding by specifying its corresponding option with no value.
+
+    Because fzf_configure_bindings erases bindings it previously installed, it can be cleanly
+    executed multiple times. Once the desired fzf_configure_bindings command has been found, add it
+    to your config.fish in order to persist the customized bindings.
+
+    In terms of validation, fzf_configure_bindings fails if passed unknown options. It expects an
+    equals sign between an option's name and value. However, it does not validate key sequences.
+
+    Pass -h or --help to print this help message and exit.
+
+EXAMPLES
+    Default bindings but bind Search Directory to Ctrl+F and Search Variables to Ctrl+Alt+V
+        \$ fzf_configure_bindings --directory=\cf --variables=\e\cv
+    Default bindings but disable Search History
+        \$ fzf_configure_bindings --history=
