multi-hops[0] should probably be mentioned as well. Using those one can for example open a file using sudo via ssh:

    /ssh:you@remotehost|sudo:remotehost:/path

Doing any further actions on a file opened that way also applies the hops there as well. For the example above opening a shell or running a shell-command would run those through sudo on the remote host.

It's worth mentioning that this is not limited to SSH followed by sudo. It can also be used to edit remote files through a bastion host, by just adding more SSH hops to the file path.
