我仔细看了eaf的wiki里关于latex的那一段。似乎是开启了synctex。
(add-to-list 'load-path "~/emacs/emacs-application-framework/")
(require 'eaf)
(eaf-setq eaf-browser-dark-mode "true")
(eaf-setq eaf-terminal-dark-mode "false")
(eaf-setq eaf-mindmap-dark-mode "follow") ; default option
(eaf-setq eaf-pdf-dark-mode "ignore")
(eaf-setq eaf-browser-enable-adblocker "true")
(eaf-bind-key scroll_up "C-n" eaf-pdf-viewer-keybinding)
(eaf-bind-key scroll_down "C-p" eaf-pdf-viewer-keybinding)
;; from TeX-pdf-tools-sync-view
;;;###autoload
(defun TeX-eaf-sync-view()
(unless (fboundp 'eaf-open)
(error "EAF is not available!"))
(let* ((pdf (TeX-active-master (TeX-output-extension)))
(url (expand-file-name pdf))
(app-name "pdf-viewer")
(exists-eaf-buffer)
(eaf-buffer-window))
(catch 'found-match-buffer
(dolist (buffer (buffer-list))
(set-buffer buffer)
(when (equal major-mode 'eaf-mode)
(when (and (string= buffer-url url)
(string= buffer-app-name app-name))
(setq exists-eaf-buffer buffer)
(setq eaf-buffer-window (get-buffer-window exists-eaf-buffer))
(throw 'found-match-buffer t)))))
(if (and exists-eaf-buffer eaf-buffer-window)
(pop-to-buffer exists-eaf-buffer)
(eaf-open url app-name "--synctex_on=True"))))
(eval-after-load "tex"
'(progn
(add-to-list 'TeX-view-program-list '("eaf" TeX-eaf-sync-view))
(add-to-list 'TeX-view-program-selection '(output-pdf "eaf"))
))
但恕我愚钝，实在找不到synctex相关的function和keybind在哪里（其实就需要两个，forward search和backward search）。在自己的emacs运行之后也是完全找不到这个功能。
可否指教？
