.SH STATUS BAR
The information displayed on the left side of the status bar can be replaced
with the output of a user-provided script, which is called by sxiv whenever an
image gets loaded. The path of this script is
.I $XDG_CONFIG_HOME/sxiv/exec/image-info
and the arguments given to it are: 1) path to image file, 2) image width,
3) image height.
.P
There is also an example script installed together with sxiv as
.IR PREFIX/share/sxiv/exec/image-info .
.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 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.
sxiv(1) will block until the handler 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.

There is also an example script installed together with sxiv as
.IR PREFIX/share/sxiv/exec/key-handler .
.SH THUMBNAIL CACHING
sxiv stores all thumbnails under
.IR $XDG_CACHE_HOME/sxiv/ .
.P
Use the command line option
.I \-c
to remove all orphaned cache files. Additionally, run the following command
afterwards inside the cache directory to remove empty subdirectories:
.P
.RS
find . \-depth \-type d \-empty ! \-name '.' \-exec rmdir {} \\;
