+## For highlight (groups) explorations, use `:lua require('telescope.builtin').highlights`
+
+`:h telescope.builtin.highlights`. It's a winner in exploring the highlights
+compared to `:highlight` that vomits to `:messages`-like interface that you
+can't search
+
+## Jump around diagnostics

+
+`:lua require("telescope.builtin").diagnostics {bufnr = <number | 0: current buffer | nil: all buffers}`
+
+`:TroubleToggle loclist`
+`:TroubleToggle workspace_diagnostics`
