The code for the various symbols vary according to the typeface, (commonly miscalled font), being used.

They also differ between Windows and Mac.

If you can locate the character map on your computer, then holding the cursor over the symbol you wish, and in the typeface you want, some text will appear giving the keys to be pressed to get that character.

U+221A means 'hold down upper case U, and type in 221A.

Simpler of course is to just select and paste.

It doesn't appear as a button on a keyboard. What you do is hold down the Alt key and on the number pad type in 251 and then let go of Alt. It should then generate the root symbol √. This is what's known as an "alt-code" and there are quite a lot of them to make all sorts of symbols not normally found on the board. You can find a list of alt-codes in the related links section.
