I don't my think it is in the latest Keynote, but you _can_ copy equations in Pages and paste them into Keynote (and Numbers)

From limited testing, it looks you can round-trip them, too: if you copy an equation in Keynote and paste it back into Pages, you get an equation that you can edit.

So, it seems it shouldn't be hard to add this to Keynote.

I found that using the LaTeXiT app that comes with the MacTex distribution is pretty easy; it offers drag-and-drop of an image into Keynote / Pages.

Perhaps more important is the ability to drag-and-drop a rendered equation from Keynote back to LaTeXiT and still be able to edit it. Pleasantly surprised when I discovered this feature.

I did not know this! Fantastic. Thanks a lot.

Ditto! This has been my workflow for a couple years now. LaTeXit is great. Almost completely replaced Beamer for me. However, if the integration is good, and I could do it all in Keynote, it would be even better.

Whoa, that would be a real game changer. It gives one hope that the Mac will be seen again as a "pro" platform.

But realistically speaking, I think they're just doing it because Word supports LaTeX syntax already.

I think if that were the reason they would have done it 10 years ago, when Word 2007 introduced that feature.

Looks nice. Any decent equivalent for Windows?

I'd for sure consider dropping Beamer if this happened.

I'm dying for this feature. Beamer is great until you want to include a video, then your life fills with pain.
