Task using selected file in ProjectPanel

[christophevg]

As a very recent former-TextMate-addict, now happy-to-have-found-Zed-newbie, I'm customising Zed to mimic my TM experience. I've found a lot and more, yet I'm blocked when trying to create a task that needs access to the currently selected file in de project panel.

What I want to achieve is the "space triggers quick view" on MacOS in TM. TM reuses (I guess) a Finder view, which includes this standard behaviour and it works great to quickly preview any file.

So, I want to create a task like:

{
    "label": "Quickview file",
    "command": "qlmanage -p",
    "args": ["$ZED_FILE"],
    "hide": "always"
  }

But $ZED_FILE points to the current file in the editor. I'm looking for a way to pass the currently selected file in the project panel.

Thanks for any pointers.
