Enabling Internal Mode

There are useful tools, such as the Internal Actions menu, that are only visible if internal mode is enabled in IntelliJ IDEA.

Setting Internal Mode in the IDE Properties File

There are multiple ways to enable internal mode, but the simplest is within IntelliJ IDEA:

Start IntelliJ IDEA.
From the main menu, select Help | Edit Custom Properties. This selection opens IntelliJ IDEA's idea.properties file. If it does not exist, IntelliJ IDEA will prompt to create one.
Add the line shown below to the idea.properties file:

idea.is.internal=true

The Internal Actions menu is available in Tools | Internal Actions.
