Okay, I think Harrie cleaned up the mess I made a while ago, so I'm just going to make a single post on this and put it more or less where it belongs this time, LOL.
These are my alphanumeric AutoCorrect entries for various symbols, so I can enter them quickly without remembering the Alt+numeric keypad codes or taking my hand off the main keyboard.
== – (en dash - Windows own code)
a--b — (em dash - Windows own code)
`` ²
``` ³ (the Autocorrect code for this is "²`", since Autocorrect will convert the first two ``hit into ² before you hit the 3rd one.)
@@ µ
## £
$$ €
&& ¢
%14 ¼ (and similarly for ⅛ ⅓ ¼ ⅜ ½ ⅝ ⅔ ¾ ⅞)
^^ º
/\ ∆
/^ ↑
^\ ↓
/= ≠
<= ≤
>= ≥
+- ±
<< ‹
<<< « (again, AutoCorrect for this is ‹< to account for the conversion after the first 2 keystrokes)
>> ›
>>> »

~~~ Pilcrow (paragraph mark)
Last, but not least, %% is for a non-breaking hyphen and !! for a non-breaking space, which must both be entered as formatted text.
