How do you get special symbols, subscripts, etc. into an answer?

make a text file with the symbols in it, and copy-paste from there to the text box.

º ≈ ± ≠ ⁰ ¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹ ₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉ ⁻³

There are three ways (that I know of)

alt+number (press & hold down alt key then using numeric keypad type the number)

alt+26 → "→"

alt+227 → π

alt+248 →°

alt+251 → √

alt+253 → ²

note that you'll get a different set if you use a four character code

alt + 0177 ± but alt+177 ▒

cut and paste ¢. I have an app called charmap.exe on my PC. not sure if it came with vista or I imported it. I've used it for years. Look under programs accessories system tools. be sure to select and then copy in two steps...

using the following code types → &larr ; but without the space ←

larr of course stands for "left arrow"

try int, nabla, uarr, and part too. I'll send you the list if you send me your e-mail since the link I got them from is no longer working. I'm pretty sure you can get this info all over the Web however...

I now use a word document and keep all these on it.

charmap is too repetitive (too many fonts), but the others are not layed out very well.

Oh I forgot the &x; codes show up after encoding, so they won't appear until they are sent or something. For instance in Yahoo answers the code appears until you preview then the symbol appears.

I get them from Microsoft Word, under "insert".
