+With \fBexecute(...)\fR action, you can execute arbitrary commands without
+leaving fzf. For example, you can turn fzf into a simple file browser by
+binding \fBenter\fR key to \fBless\fR command like follows.
+
+    \fBfzf --bind "enter:execute(less {})"\fR
+
+\fB{}\fR is the placeholder for the quoted string of the current line.
+If the command contains parentheses, you can use any of the following
+alternative notations to avoid parse errors.
+
+    \fBexecute[...]\fR
+    \fBexecute~...~\fR
+    \fBexecute!...!\fR
+    \fBexecute@...@\fR
+    \fBexecute#...#\fR
+    \fBexecute$...$\fR
+    \fBexecute%...%\fR
+    \fBexecute^...^\fR
+    \fBexecute&...&\fR
+    \fBexecute*...*\fR
+    \fBexecute;...;\fR
+    \fBexecute/.../\fR
+    \fBexecute|...|\fR
+    \fBexecute:...\fR
+.RS
+This is the special form that frees you from parse errors as it does not expect
+the closing character. The catch is that it should be the last one in the
+comma-separated list.
+.RE
+
+\fBexecute-multi(...)\fR is an alternative action that executes the command
+with the selected entries when multi-select is enabled (\fB--multi\fR). With
+this action, \fB{}\fR is replaced with the quoted strings of the selected
+entries separated by spaces.
