Feature Request: possibility to specify key config file via command line argument

[griai]

I use feh extensively to trigger all kinds of different actions on images. (For example, I execute scripts via actions in order to sort or label images quickly.) For different projects, I often need different key bindings. Instead of always copying or linking the appropriate key config file, it would be preferable if one could just choose one per command line argument.

Would adjusting XDG_CONFIG_HOME work for you? It's already supported, but has the downside of affecting the entire feh config, so you'd need to duplicate / symlink your themes file, if present.
