Miro is a native PDF viewer designed for efficient document reading through customizable keyboard and mouse controls. It supports Windows, macOS, and Linux, including Wayland and X11 desktop environments. Its default Vim-style shortcuts enable rapid navigation without relying on graphical menus. Users can open multiple documents in tabs, search using regular expressions, and navigate bookmarks or internal links. A document overview displays pages in a grid for quickly locating content. Automatic file reloading updates open documents when their underlying files change, making it useful for LaTeX and Typst workflows. Dark mode can be applied independently to the interface and PDF pages. Additional capabilities include annotation viewing, presentation mode, jumplists, and optional remote control through an RPC server.
