zoom (narrow) in and out of specific sub-object

[aspiers]

According to PaulJuliusMartinez/jless#80 (comment), fx has (or at least had) a feature for zooming into a sub-object, so that you only see that part of the tree. In other words, that path temporarily becomes the new root, and you can "unzoom" (exit) back to the full object afterwards. However I can't find that feature in https://fx.wtf/key-bindings or anywhere else. Was it removed? This would be a super helpful feature, especially for large objects!

You can use p (preview) feature right now. This is not exactly the same, but can be used for complex json object.

Another feature is queries: fx data.json .some.path | fx.

And I'm working right now on adding interactive queries, see

fx/query.go

Lines 3 to 6 in 5031b2e

	func (m *model) doQuery(query string) {
	//args := []string{query}
	//exitCode := engine.Start(parser, args, opts)
	}

Thanks - yeah I found the preview feature, but I'd really like to be able to narrow to a sub-object within a large object via a single keystroke and then navigate around that interactively as normal. Interactive queries sounds really cool for other use cases, but for this particular use case, having to manually construct a query which matches the sub-object you want to zoom into would be too much cognitive overhead to be useful.
