Besides Googling for tricks, another way of learning LaTeX is to download the source code for nice-looking papers that you find on the arXiv. For example, for "Learning to learn by gradient descent by gradient descent" arXiv:1606.04474 (https://arxiv.org/abs/1606.04474 https://arxiv.org/abs/1606.04474), if you click on Download->Other formats, you get the latex source code and in this case also the Omnigraffle files for the diagrams.
