Open or view

Open or view opens fman's internal viewer on the file under the cursor, the same as View file — but falls back to the normal open action whenever the internal viewer cannot handle the target, instead of showing an alert.

It exists for people who want the internal viewer as their default open action without losing folder navigation, and without binaries such as .exe or .zip being garbled by the text viewer.

Setting it up

There is no default binding — opt in from your own Key Bindings (<OS>).json. The usual setup swaps the default Enter and Shift+Enter roles:

[{ "keys": ["Enter"], "command": "open_or_view" },
 { "keys": ["Shift+Enter"], "command": "open" }]

With that, Enter opens files in the internal viewer and still navigates into folders, and Shift+Enter becomes the normal open-with-the-OS action.
