+
+# Example for $XDG_CONFIG_HOME/nsxiv/exec/key-handler
+# Called by nsxiv(1) after the external prefix key (C-x by default) is pressed.
+# The next key combo is passed as its first argument. Passed via stdin are the
+# images to act upon: all marked images, if in thumbnail mode and at least one
+# image has been marked, otherwise the current image. nsxiv(1) will block until
+# the handler terminates. It then checks which images have been modified and
+# reloads them.
+
+# By default nsxiv(1) will send one image per-line to stdin, however when using
+# -0 the image list will be NULL separated and the environment variable
+# "$NSXIV_USING_NULL" will be set to 1.
+
+# 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.
+# If KEY has an uppercase equivalent, S-KEY is resolved into it. For instance,
+# K replaces S-k and Scedilla replaces S-scedilla, but S-Delete is sent as-is.
