Open object with external tool

[abiratur]

I am working with multiple data file formats such as avro, csv, parquet etc.
I would like to have an option to open those files with a configurable external tool (i use vscode with extensions)
I was thinking of implementing this as another keybind 'o' and open with whatever is configured in EDITOR / config file.

Yes, this is one of the features we are hoping to implement in the near future.

Bump. Would love this feature as the builtin previewer cannot correctly format parquet files
