+.SH "USING SELECTOR IN BASH"
+
+The selector command comes with a shell script for bash. If you add
+
+.P
+.nf
+.B source bash-selector.sh --hist --cd
+
+.fi
+in your \fB~/.bashrc\fR, it will remap M-r to the smart history search,
+and redefine \fBcd\fR so that M-c provides a smart cd history.
+
+This script relies on readline being configured with the default
+emacs-style key bindings. You may have to hack a bit if you want to
+use it with the vi-style mode.
