While LaTeX is a great typesetting language and system, it isn't always easy to find the right LaTeX commands for the symbol you need.

Of course, you can always search on the web or look through one of the many lists of LaTeX symbol tables (e.g., all 338 pages in this example)

However, a neat tool exists that allows you to draw your desired symbol and provides suggestions on which symbol\command pair it might be.

For when you just can't find the right command, it can be a real timesaver!
