Maybe not mind blowing, but just a few examples from my (very normal) day:
I wrote a statement in Rider that used a class that didn't exist. So I hit Alt+Enter with my cursor there, and had it create me a class. Then I hit Alt+Enter on that class and had it move it to a separate file. Then I added the base class it should inherit from, hit Alt+Enter, and had it scaffold out all the methods I need to override. About fifteen or twenty seconds with a modern IDE and didn't require any of my intellectual capacity to actually execute.
I realized that another class in this multi-GB codebase had a typo in its name, and hit Shift+F6 to rename it. Typed in the correct name, and twiddled my thumb for two or three minutes while it renamed every instance in the codebase.
Found a file that used a declaration style that's against our coding style. Hit Alt+Enter on one example, told Rider to configure the project to always prefer the other style and replace all examples in the file.
None of those are particularly magic, but having so many of them that are completely reliable a context menu away makes an enormous difference. Also with a recent file list popup and really excellent code navigation, I find that I don't keep a file list or tabs open at all. I just jump to symbols and toggle back and forth between the last couple of files.
