+.SS PREVIEW BINDING
+
+With \fBpreview(...)\fR action, you can specify multiple different preview
+commands in addition to the default preview command given by \fB--preview\fR
+option.
+
+e.g.
+
+     # Default preview command with an extra preview binding
+     fzf --preview 'file {}' --bind '?:preview:cat {}'
+
+     # A preview binding with no default preview command
+     # (Preview window is initially empty)
+     fzf --bind '?:preview:cat {}'
+
+     # Preview window hidden by default, it appears when you first hit '?'
+     fzf --bind '?:preview:cat {}' --preview-window hidden
