Below is my tiny cheat sheet for PhpStorm. Knowing and using hot keys improves productivity significantly. I used to use them before started using IdeaVim, as many of these hot keys conflict with Vim bindings.

This post was in drafts here for at least three years, and it bubbled up during my last revision. I decided to publish it in case it is useful for someone.

Recently, I was forced to move out from PhpStorm and other JetBrains products, because Russian citizens aren’t eligible to pay for various products and services. I was a loyal customer of JetBrains products for years, and now, when my last two-years license was about to end, I had to consider moving to something else. I used IdeaVim plugin for the last few years, and moving to NeoVim was natural for me.

Refactorings
