Hey Stephan,

I can not answer where to find that file on windows, but the first hit
with google: https://stackoverflow.com/a/56536275

You can also set these options directly on the command line:
```
ssh -o IdentityAgent='%d/.gnupg/S.gpg-agent.ssh' -o
ProxyJump=jumpserver.example.net targethost.example.org
```

I'm not sure if you really have to set the IdentityAgent if your GPG and
SSH Agent Socket is setup correctly...

Do you see something with `ssh-add -L`? If yes, then you should not have
a need to set IdentityAgent for a Host. (Only if you have multiple
Agents or you have to specify it only for certain hosts etc etc but if
its your only Agent and you have no special requirements, then just
leave it out IF `ssh-add -L` shows you the key from your card.)

Good luck,
Bernd
