PyCharm is extended through plugins, and one can install them by simply browsing the Plugins catalog in PyCharm:

The PyCharm plugin ecosystem is so large and so important that there is an entire chapter dedicated to it in this book. However, in this section, we will look at two plugins in particular: IdeaVim and emacsIDEAs.

IdeaVim was created by JetBrains. It offers full emulation of Vim and is freely available on the repositories.

However, the other plugin, emacsIDEAs, is not supported by JetBrains. This is a third-party plugin, but has a high rating and is regularly updated.
