nsxiv/exec/key-handler

#!/bin/sh

# Example for $XDG_CONFIG_HOME/sxiv/exec/key-handler
# Called by sxiv(1) after the external prefix key (C-x by default) is pressed.
# The next key combo is passed as its first argument, followed by the paths of
# all marked images or the path of the current image, if no image is marked.
# sxiv(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.
