I was playing DF before RimWorld so it had clicked before RimWorld even existed. Then the Steam version came out and I had to relearn everything because it didn't have the keyboard commands anymore and they rearranged the menus. lol
My RimWorld is modded up to be closer to DF, too. The only one that's kinda wonky is the layers mod that makes it "3D" like DF is. It is as close to "sci Fi DF" as I can make without making my own game (which I also am working on).
