Equations in Keynote in a browser I am trying to see if I can add equations in Keynote in iCloud via browser (I don't have a Mac/Iphone). I searched but couldn't find a way other than copy-pasting an image from somewhere.
(I'm using Chrome, and I couldn't do it neither in Linux nor in Windows)

A similar question is about sub/super-scripts. I could not find a way to insert them either in a browser.
This reference may help.

For sub/superscripts, it says there is a keyboard shortcut for windows:  Control-Alt-Minus/Plus.

(Can't test this myself)
