We've been using bookdown for our RStudio admin guides (http://docs.rstudio.com) for years, but I only realized when looking at #657 that you can use the arrow keys to move between search results within a section - this isn't how search functions work in most other instances (e.g. in your browser) and it's not likely that users are going to know that it's an option unless they know that the doc was written in bookdown (and that this is how search works in bookdown!).

It'd be great if some additional UI could be added here to add clickable arrows to make it clear that you can move up/down through the available search results, similar to how it appears when doing a simple Ctrl-F in your browser:
