+.SH EXTERNAL KEY HANDLER
+Additional external keyboard commands can be defined using a handler program
+located in
+.IR $XDG_CONFIG_HOME/sxiv/exec/key-handler .
+The handler is invoked by pressing
+.BR Ctrl-x .
+The next key combo is then passed as its first argument and the path of the
+current image as its second argument.  sxiv(1) will block until the handler
+terminates. It then checks if the image has been modified and reloads it.
+
+The key combo argument has the following form: "[C-][M-][S-]KEY",
+where C/M/S indicate Ctrl/Meta(Alt)/Shift modifier states and KEY is the X
+keysym as listed in /usr/include/X11/keysymdef.h without the "XK_" prefix.
