I might be the last person in the world to find out, but I just found a website, Detexify, that clearly works on magic. You draw a symbol, and it looks for the closest Latex symbol. It works surprisingly well. I just draw a terrible approximation of the Weierstrass p symbol, and the actual Weierstrass p symbol was the 4th hit.

Indeed, you are the last person on Earth to discover Detexify.

Don’t worry, you’re not the last one – I just told one of my professors about DeTeXify a few days ago, and I had to explain how to draw with the cursor too.
Damn it, that’s worse. If I were the very last, then I would be special. Now, I’m not even that.
I rarely need to look up symbols any more but what I like about Detexify is that it gives a list of symbols that are also close to the symbol you are looking for, even if they are not in the same category, so sometimes it helps me learn about new interesting symbols that I might have use for in the future, but never would have thought to look up otherwise.
I’m the last one now
I might be the last. Thanks..super cool
