I keep discovering keyboard shortcuts that are not listed anywhere under preferences. For example, I discovered here that ⌥ ALT⌘ CmdE will eject all partitions on a disk when a partition is selected. How the heck do people find these shortcuts, and where can I find more?

Not sure if this is a complete list, but this is a pretty good start from Apple:


Here is another link to an image of the shortcuts:


  • Unfortunately, neither shows ⌥⌘E! (Only the unmodified ⌘E is listed on the first link.)

Quite a few keyboard shortcuts vary on different Macs, especially the laptops, so that is one good reason it is not easy to find a 100% complete list.

There is a super in-depth guide, here which was designed to show developers which shortcuts not to use, but seems to be the best go-to guide for the comprehensive ins-and-outs of keyboard shortcuts in OSX.

I'd also reccommend browsing around more on that same site (https://developer.apple.com), although I didn't see a definitive shortcut guide yet.

I've learned about many of the shortcut keys (including the ⌥-modifiers like the one you describe) by reading through the Apple Pro Training Series books, by Peachpit Press.
