Sure!
This {*} is an asterisk. I make it with shift-8 (same as you do).
This {•} is a bullet. I make it with option-8.
This {°} is a degrees sign (as in temperature). shift-option-8.
This { } is a non-breaking space. option-spacebar.
This {¢} is a cent sign. option-4, similar to the Shift-4 that makes the $ sign.
This accented e {é} is option-e followed by e again
(is that one the grave? I always get the names confused. Anyway…) You see the letter e with that particular accent more often than other vowels, but sometimes other vowels do take that accent.
This accented i {í} is option-e followed by i
This accented a {á} is option-e followed by a
This accented o {ó} is option-e followed by o
This accented u {ú} is option-e followed by u.
Want umlauts? {ü} is option-u followed by u.
Option-u followed by other vowels such as o {ö} = same.
The French c with the descender-thingie, whatever it is called? {ç} is option-c
The spanish tilde-thingie that goes over the n? {ñ} option-n followed by n. Option-n followed by other appropriate letters puts a similar ˜ over them too. And I just put one by itself by going option-n followed by space.
Ý is option-t
å is option-a. ß, the German es-tzet thingie, is option-s.
The en-dash {–} is option dash. The em-dash {—} is option-shift-dash.
The scriptlike f {ƒ} commonly used on the Mac to mean “folder” is option-f
The division sign {÷} is option-slash.
The upside-down exclamation point {¡} is option-1.
The upside-down question mark {¿} is shift-option-slash (or option-questionmark if you prefer).
The “not equal” sign {*} is option-equals.
The less-than-or-equals sign {*} is option-<
The greater-than-or-equals sign {*} is option->
The yen sign {¥} is option-y.
Some of ours are a bit less intuitive, but are still easy to remember if you use them much:
curly quotes [“”] are option [ and option-shift [ respectively.
curly single quotes [‘’] are option ] and option-shift ] respectively.
The omega {*} is option-z.
Copyright {©} is option-g (option-c being already taken; look at a capital G and look at a ©…I guess it is supposed to be similar?)
The ellipsis {…} is option-semicolon.
The European quotation marks {«»} are option-backslash and option-shift-backslash, respectively.
One cool thing about the ASCII escapes is that you can add any multiple of 256 to a number and it still works. Alt+0162 too hard to remember? How about Alt+04002, Alt+021666, or Alt+023458?
