How to “Save As” in Apple Keynote

For a very long time, I've had just one gripe about designing in Apple Keynote for presentations. Seriously, just ONE gripe: I can't stand the "File > Duplicate" feature. Even though it's so minor, and you can basically get the same effect, I've experience that the duplicate feature seems to add a extra few steps to my workflow. I like to create tons of versions as I go—”kind of a poor man's version control. But with Duplicate, I end up confusing myself, working in the wrong file, smashing things, and crying.

Why Apple couldn't simply embrace the "Save As" functionality has been a mystery to me, and just when I almost gave up, Google saved the day.

Here's the stupid-simple trick I discovered on some nerd forum which enables "Save As" in Keynote. When you open the File menu, press and hold the "Option" key on your keyboard and WHAHLAH: that pesky Duplicate feature is replaced by our main man Save As.

Here's a little screencast in case you didn't follow. My first screencast, so please, bare with me.

Save As on my friends!
