Same here.  I can't see how it could operate differently, so I'm
wondering if this is just confusion of expectations.

Oleh, when you say "everything works", do you mean everything listed in
the README?  The thing the OP is saying doesn't work is not mentioned in
the docs, e.g., it says

    - Start zooming in with <f2> g

It never says "hit <f2> and *immediately* get prompted".
