Are there good comprehensive lists of LaTeX commands online?

I'm relatively new to actual LaTeX scripting, much of my experience comes from using MathJax over at math.stackexchange.com and I'm kinda self-taught, just picking things up as I need them. However, I'd like to write an entire paper in LaTeX now and I need to do a bit more than MathJax offers to me, such as page allignment, font selection, etc. However, it would be nice to view a list of all (or most) the commands, preferably categorized and easy to navigate. Does such a place exist and where can I find them?

I don’t know if there is a list of all commands available, but there is at least the Comprehensive LaTeX Symbols List. You have an exhaustive reference of mathematical and text symbols for a wide range of packages.

For the rest of the commands, the package documentations have an index of the commands defined. Maybe it is possible to parse the PDF files with a custom script which will make a more accessible list.
