+Put a window into list choice mode, allowing
+.Ar items
+to be selected.
+.Ar items
+can be a comma-separated list to display more than one item.
+If an item has spaces, that entry must be quoted.
+After an item is chosen,
+.Ql %%
+is replaced by the chosen item in the
+.Ar template
+and the result is executed as a command.
+If
+.Ar template
+is not given, "run-shell '%%'" is used.
+.Ar items
+also accepts format specifiers.
