IntelliJ IDEA: how to revoke reformat code / optimize imports dialog?

Question

So I've pressed Do not show this dialog in the future (screenshot taken from the web).

It's been a while and now I want to change default reformat behavior.

I can't seem to find an option to show this dialog again.

Answer 1

Update 2015/10:

In current versions of IntelliJ (and likely Android studio and other IntelliJ based IDEs) there no longer seems to be this option as it is not needed.

⌘ + Alt + L no longer shows the dialog, instead it directly reformats the file and gives you a hint that you can display the dialog using ⌘ + Alt + Shift + L . That dialog no longer includes Do not show again option.

For older IntelliJ versions these dialogs can be re-enabled in Settings/Editor/General :

可以在“格式化”部分的“设置/编辑器”下找到更新版本的IntelliJ或Android工作室
