Same bindings in different contexts?

[eqyiel]

I'm really used to the ido-style next/forward using C-s and C-r, so I'd like to bind those to prompt-next-completion and prompt-previous-completion when tanything is open.

The relevant section of my config file looks like this:

plugins.options["tanything_opt.keymap"] = {
    "C-s": "prompt-next-completion",
    "C-r": "prompt-previous-completion"
};

It looks like those keystrokes are getting stolen by command.iSearchForwardKs and command.iSearchBackwardKs. Is it possible to achieve this and keep the regular behaviour of those keys when tanything is not focused?

Thanks for Keysnail!
