Great, thanks for the pointers!

Quick Look in this case is the quick open of files through finder by tapping 'Space'. Might be some equivalents, i'll look around.

There's an extension for gnome called either Gnome-Look or Sushi, can't look up which it is right now.

Yes, Gnome Sushi for "press space for preview"
