key strokes for xnview/linux

[uduun]

hello,

I tried to solve this without bothering the community, but either I'm too dumb or there in fact is no information about this (or at least difficult to obtain): Could anybody please tell me how to configure key strokes for xnview in the linux version? I installed the latest version in Ubuntu and don't see how to customize xnview at all (the options menu doesn't do it and i can't find some kind of *.ini file or something).

any help will be appreciated, thank you
