SUMMARY Unlike other PDF viewers like Sumatra PDF reader, Okular lacks the ability of quickly shifting with a keyboard shortcut to the next PDF available within the same directory than the opened one. It would be really nice if this capability could be added. STEPS TO REPRODUCE 1. Create a folder with very similar PDF files, one called a.pdf and the other called b.pdf 2. Open a.pdf in Okular 3. Press CTRL+SHIFT+Left and CTRL+SHIFT+Right repeatedly to quickly browse between them OBSERVED RESULT Nothing happens EXPECTED RESULT It would be a nice enhancement if Okular would close the current one and open the next one automatically, for facilitating the comparison between them.
