Does anyone know how to get symbols, such as alpha etc. into your posts without using latex?

Look for the Greek letters in the second table. I've also seen people use other symbols not in that page, partial d, for example.

The symbols don't match the numbers...

Here's part of a table from

One could copy from the tables above [or this post] and paste into a message being composed.

Firstly, apologies for reviving a dead thread. Secondly, how difficult would it be to add a menu for inserting HTML entities into posts, similar to the LaTeX menu recently added? When typing a response, it isn't always necessary to use the presentation power of LaTeX for the odd Greek symbol or equation, however it's a bit of a pain to look up the decimal codes for various HTML entities. A quick drop down menu (maybe of just the Greek symbols) would make life much easier for writing short equations or for those no familiar with LaTeX, perhaps it would also reduce the unnecessary load on the server.

Just a thought.

I'm not so fond of memorizing complex hotkeys, so I like this advice from the bottom of the page of Kurdt's link:
