Yeah code folding works for the visual scrub, but it's the "search within" feature that's missing. An example of my common use case is digging through a Bosh manifest file for a resource with a particular name, then finding, say, the VM type associated with that resource. The name and vm_type fields may be separated by hundreds of lines (it's a machine-generated file that does not retain element order), but they're siblings of each other. In vim, I could land on the first { and then hit: v% (extend selection to matching delimiter) /\%Vvmtype: (to search for "vmtype:" within the selection). In IntelliJ I could similarly extend a selection between delimiters and then search within it. It's absolutely correct that this is a tooling problem. You could imagine a YML plugin for IntelliJ or vim smart enough to offer a motion for "select all the children of this block," but AFAICT no such tool exists.
