+External Pipe
+=============
+
+Description
+-----------
+
+This patch lets you write st's screen text out through a pipe, for example,
+url-select (below).
+
+Example
+-------
+
+Bind alt+u to extract all visible urls and present dmenu, to choose and open
+said urls:
+
+ static Shortcut shortcuts[] = {
+ ...
+ { MODKEY, 'u', externalpipe, { .s = "xurls | dmenu -l 10 | xargs -r open" } },
+ };
+
+
+([xurls][1] and [open][2] are external scripts)
+
