Change Stack Code Peek
|
Change Stack now supports Code Peek: click a variable, function, class, or type name to look up its definition and usages. Code Peek uses GitHub code search to show likely definitions and references with surrounding context, so you can follow the code without leaving the review.
When a result points to a changed file in the pull request, Open in Change Stack jumps to that file. Change Stack keeps an in-page back trail so you can return to where you started.
See the Change Stack documentation for details.
