Here are Mac keyboard directions for various symbols. (Many of these also work in Windows I’m told.) The idea of doing this was prompted by this post from Medium. The Oxford English Dictionary does not recognize this sense of the word, which probably means that its typographical meaning (approximately, “symbol additional to the regular alphabet”) is of recent invention. I resist the modern temptation to say “coinage” here, as this would be wrong. The phrase “to coin a phrase” is an IRONIC usage, usually preceding a cliché. “To coin” in the context of a word would mean “to invent”, and so would only be applicable to the very first use of glyph to mean something more specific than “a sculptured mark or symbol”. The OED is regularly revised on-line now, but hasn’t got to this part yet.  It’s a bit like the Forth Bridge; you have to finish painting it the first time before you can start repainting it.

I have not figured out how to do superscripts and subscripts yet. I suspect they may not come on the system, but require some sort of mathematical program. But if anyone knows how to do these, please let me know via “Comments”.

⅛ and other case fractions can be created by going to System Preferences>Personal>Language & Text>Text then clicking the required boxes. Whenever you type 1 / 8 or whatever (without those spaces) the system will automatically correct to the case fraction.

`  grave accent allowing you to add a letter under it — Option-`  (it’ll come up with a shaded box around it; type the letter you want before the box disappears)

´ accute accent — Option-e (same shaded box)

ˆ circumflex accent — Option-i (same shaded box)

¨  umlaut, dieresis  — Option-u (same shaded box)

Ō  macron — Option-A (option-a for lower case) (same shaded box)*

þ  thorn — Option-t (Extended Keyboard)

ð  eth — Option-d  (Extended Keyboard)

🚰 An alarmingly large number of symbols may be obtained by going to Special Characters under the Edit menu at the top of your screen. Included are lots of Emojis, among them this Potable water icon. Who needs this so much that it’s made available ahead of sups. and infs.?

This link takes you to a “complete list of special character keyboard shortcuts” for the Mac from The Design Cubicle.

*You need to activate US Extended Keyboard to get this. To do so go to the Apple Menu, select System Preferences>Language & Text>Input Sources, then scroll down the options and click on US Extended. (Don’t unclick any others — you can live with several optional keyboards.) Then when you need to access Extended Keyboard, click the US flag icon at the top right of the screen and select the Keyboard from the options offered in the drop-down menu. When you’ve done, switch back to your regular keyboard.

Option-Shift-h will deliver a list of Keyboard Shortcuts.
