The best PDF viewer ever
  • <C-r> will “recolor” the document, (mostly) inverting the colors in a PDF. This more or less acts as a PDF dark mode
    • Can set specific light and dark colors with set recolor-<dark/light>color "#<hex>"
  • s: fits the page to the width of the viewer, almost always what I want
  • a: fits the page size to the viewer
