Keir Thomas, writing for Mac King Fu:

I’ve been using Mac OS X for over a decade and have written books about how to use it, but today learned of a new way of opening files via the App Switcher.

Boy, did I feel dumb.

To be fair to Keir, I did not know that one either.

So, I thought it fun to write one of those Wikipedia-style posts about every possible way to open a file on Mac OS X – or at least every method that I’m aware of. See how many you know.

Great post, worth it to scan through, tuck away, and pass along.
