Again, I would recommend copying them from an existing page on the Internet such as a physics paper on the subject that is not a singular image or primitive PDF file, but rather a web page or more advanced PDF that let's you select characters. unless you can find a cheat sheet somewhere for the needed notation (I tried) is really a pain though. If you need more information on a specific topic, please follow the link on the corresponding heading to access the full article or head to the guide. On pressing the last of the four, the character 〉 appears you can then release the option key. This page provides an overall cheat sheet of all the capabilities of RegExp syntax by aggregating the content of the articles in the RegExp guide. While you are switched to Unicode Hex Input, to place U+3009 (the "decomposition" code, not the main 232A code) into your document, hold down the option key and – while holding it down – tap the four keys 3, 0, 0, and 9 in sequence. This will allow you to type unicode codes via your Mac keyboard for your Bra-Ket notation, but you'd have to look up the individual codes and then type them in. You can then click the flag by the clock that will now be showing, and change it to your new input: The ultimate possibility is to install the Mac's Unicode keyboard an input source by going to > System Preferences > Keyboard icon > Input Sources, and add the Unicode Hex Input and check the box to Show Input menu in menu bar.

I think the easiest thing is to simply copy them from a document online that uses them (and uses them as real characters, not as images) and paste them in. Apples equation support in Pages, Numbers, and Keynote relies on a minimalistic, compiled Blahtex translator that converts LaTeX and MathML codes into document objects. Apple does have a help guide here, though I am not sure if it has what you need:Ībout LaTeX and MathML support in Pages, Numbers, Keynote, and iBooks Author - Apple Support
