• Frequent switching between different buffers is inconvenient, so I’ve started to use multiple frames to maintain different working scenarios, such as taking work journal, programming in C++, navigating folders in Dired mode, processing data with Julia.

  • To prevent sporadic lag or delay while I key in characters within Emacs, I restrict the maximum font-lock level for Org mode.

    (setq font-lock-maximum-decoration '((org-mode . 1) (t . t)))

  • Directly change the background color of a linked image in Org mode or edit it in Krita. This is very useful for integrating my scanned notes and sketches into Org Roam.

    (defun tjh/org-open-link-with-named-app (app)
  "Open the Org link at point with the given app."
  (let* ((link (org-element-property :path (org-element-context))))
    (start-process-shell-command "org-open-link" nil (format "%s '%s'" app link))))
