I have spent close to a decade writing about the Apple ecosystem, and I still meet people who have used Finder every single day for years without ever discovering its powerful half. Apple keeps that half hidden behind modifier keys and a handful of Terminal commands, and this cheat sheet pulls all of it into one place so you stop forgetting the good stuff.

Here is what you get:

• A two-page A4 PDF, designed to be printed and kept by your desk.

• Page one is the full modifier-key map: the Option-key menu transformations, the move-instead-of-copy trick, column-view shortcuts, Go to Folder power moves, and the Get Info trio.

• Page two is the Terminal section, with each tweak laid out as enable-then-undo, so you can try everything without any fear of breaking something.
