I'm using Lubuntu 16.04 LTS Xenial version. I tried to use gnome-sushi to preview files from PCmanFM file manager which comes built in with Lubuntu.
Hitting spacebar opens the file in the allocated application automatically (even before installing gnome-sushi). After installing sushi, hitting spacebar doesn't make any difference.
Any idea how to turn on Preview Mode instead of opening the file in respective applications?
