I want a master cheatsheet for gnome commands too. These are some of the commands I needed to memorize when working with gnome:
nautilus <-> File Manager
evince <-> Document Viewer
eog <-> Image viewer
baobab <-> Disk Usage Analyzer
nautilus <-> File Manager
evince <-> Document Viewer
eog <-> Image viewer
baobab <-> Disk Usage Analyzer
Of course I'm not even remotely in their targeted user base since I don't run GNOME, but it annoyed me nonetheless.
However I can at least remember "Finder", "Preview" whereas I can never remember "eog" and have to look in old shell scripts to find out. Worst name ever with no way to discover it.
Similarly dolphin shows "File Manager" next to it, and when I to search for "file manager" it is right at the top of the list.
