+# Example for $XDG_CONFIG_HOME/nsxiv/exec/key-handler
+# Called by nsxiv(1) after the external prefix key (C-x by default) is pressed.
+# The next key combo is passed as its first argument. Passed via stdin are the
+# images to act upon, one path per line: all marked images, if in thumbnail
+# mode and at least one image has been marked, otherwise the current image.
+# nsxiv(1) blocks until this script terminates. It then checks which images
+# have been modified and reloads them.
+
+# 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.
