^{Originally posted by dolzenko April 4, 2025} E.g. in my case I wanted a quick way to download and run custom command on the file. Or, possibly, run command with path to file on the bucket. I'm thinking something along the lines of fzf. https://github.com/junegunn/fzf Seems like the simplest thing would be to provide new keybind to output selected/downloaded path to stdout and exit
