Emacs has code peek. With lsp-mode it has that little window: https://emacs-lsp.github.io/lsp-ui/#lsp-ui-peek https://emacs-lsp.github.io/lsp-ui/#lsp-ui-peek Personally I use eglot with consult which temporarily switches the entire buffer to do the "peek" functionality rather than popping up a tiny window: https://github.com/minad/consult https://github.com/minad/consult
