I just installed LyX on a new device and noticed that, while I can manually export to a saved PDF, Ctrl+R didn't have the usual convenient effect of creating a preview PDF. I read this answer to a question about exports, and in adding the buffer-export pdf2 command I accidentally made Ctrl+R export instead of previewing. Can I analogously add a command to instead achieve preview? I tried buffer-preview pdf2 and preview pdf2, but neither worked.

  • Does buffer-view do what you want?

The LFUN to preview is buffer-view.

You can see the default bindings here. You might want to check your user directory to see if you or LyX unintentionally changed the default binding.
