So, let's say F2 does something important in an open app (e.g. "Rename file" in Explorer) - does that mean it would not work anymore?

Or am I missing something obvious?

The author sounds like they are using macOS, where the F keys aren't used much.

Yeah I use F2 constantly for rename, not just in explorer but very useful in lots of apps. In Unity (the game engine) it's invaluable. Also F3 is generally "Find next" when you have a search box open. F12 and Shift-F12 do code navigation in VS and F10 and F11 are useful in the debugger. There are lots of nice things you can do with the F keys which this tip spoils.
